What’s the beryllium copper?

Beryllium is a steel grey, strong, light-weight metal that has one of the highest melting points of the light metals. It has excellent elasticity modulus, thermal conductivity, is nonmagnetic and resists to concentrated nitric acid. Beryllium is primarily used as an alloying agent in the production of beryllium copper and more than 70 percent of the world’s total beryllium is used to produce beryllium copper.

Beryllium copper(BeCu), also known as Beryllium Bronze or Spring Copper, A alloy by adding 0.2~2.75% Beryllium and sometimes other elements in the cooper. Beryllium copper is a precipitated and aged hardened alloy. Its hardness can reach HRC38~43 after solution aging treatment, and electric conductivity is also greatly improved. The beryllium copper has a wide range of applications for where require excellent increased strength, durability, and electrical conductivity such as the molds manufacturing, explosion-proof safety tools, electronic devices and other automotive applications.

The international manufacturers of high quality beryllium copper are Ulba Metallurgical, Brushwellman(now Materion Brush) of the United States and Japan company Hinko (NGK). The general product code in the market is mainly according to ASTM standards, and the alloy material is marked with the letter C. C17000, C17200 and C17300 are the most commonly used beryllium copper materials.

Practical application of titanium alloy in 3D printing technology

Titanium, one of the widest-known alloys in Metal 3D Printing, combines excellent mechanical properties with very low specific weight. Pure titanium is available in grades one through four and all grades exhibit extreme corrosion resistance, ductility and weldability. Ti6Al4V is a titanium alloy that is 6 percent aluminum and 4 percent vanadium and it maintains its high tensile strength even at extreme temperatures. In 3D printing, they can be found a wide range of options in practical application.

 

1 Medical application

In industrial process, titanium’s biocompatibility makes the metal optional for medical applications, particularly when direct metal contact with tissue or bone is a necessity. Among the metal materials used for human hard tissue repair, Ti’s elastic modulus (about 80~110 GP) is the closest to human hard tissue, which can alleviate the mechanical inadaptability between metal implants and bone tissue. Therefore, titanium alloy has a wide application prospect in the medical field.

In the mid-20th century, the American and the United Kingdom applied pure Ti in organisms in the first time. Pure Ti has good corrosion resistance in physiological environment, mainly used for oral repair and replacement of less bearing parts, but its poor wear resistance has limited its application in bearing parts.

In 3D printing, the mechanical properties of titanium alloys Ti6Al4V(Gr5) and Ti6Al4V (Gr23) make them popular choices for clinical medicine. Compared with pure Ti, Ti6 Al4V alloy has high strength and good processability, was originally designed for aerospace applications, then is widely used in surgical repair materials such as the skull reparation, bone plate, etc. For a long time, the domestic and foreign research team focus mainly on Ti6Al4V, but the element Al and V may be harmful to human body, the new beta titanium alloy without Al and V such as TiZrNbSn, Ti24Nb4Zr7. 6 Sn etc were found.

Nowadays, 3D printing has been applied in orthopedic surgery and bone replacement. According to the data of patients, the prosthesis and auxiliary guide were printed out to help to find the incision position, perforation position, and drilling depth to simulate the surgery. The prosthesis manufactured by 3D printing technology can regenerate human tissue cells in the interspace, and the customized prosthesis is the same as the original shape of the patient’s body, and finally achieves the effect of close to the real bone after the surgery. In July 2015, thoracic surgery of TangDu hospital of China successfully performed a 3D printed titanium alloy sternum implant as a patient with the sternal tumor, becoming the world’s first 3D printed titanium alloy sternum implant. Dentistry is featured by personalized customization, rapid and lightweight miniaturization, which is especially suitable for adopting metal powder, especially titanium alloy powder 3D printing technology. Its products include dental crowns, dental Bridges, lateral orthodontic brackets, denture brackets, and dental screws.

 

2 Molds and tooling

Titanium alloys are used to produce a wide range of components and parts such as including blades, fasteners, rings, discs, hubs and vessels. Compared with the traditional forging and casting methods, the computer-controlled 3D printing converts CAD optimally into machine code or to rule out human errors, strictly controls the size of tooling part, especially for complex parts and ultra-complex curved parts. It greatly reduces the production time of the model and mold, improves the precision and quality of the model, and reduces the production time and cost.

 

3 Aerospace & Aeronautics

Producing aircraft is becoming more efficient and cost-effective than ever because it takes quality engineering to get an aircraft up in the sky. From lightweight components to certified series production, we know that aircraft components require an unconventional touch. The high cost, complex process and long delivery time of titanium alloy products manufactured by traditional forging and casting techniques limit their application, especially in the aerospace industry where customization is required.”Lightweight” and “high strength” have been the main objectives of aerospace equipment manufacturing and development, while the metal parts produced by 3D printing fully meet their requirements for equipment.

The titanium alloy used for gearboxes and connecting rod are Ti6Al4V and Ti6Al4VEL. 3D printing technology integrates conceptual design, technical verification and production and manufacturing, which can quickly realize small-scale product innovation and shorten development time. The total amount of material was reduced by 63%. The significant weight reduction leads to a smaller carbon print and less fuel usage for airplanes. The thermal stress was reduced due to less bulk material and larger support areas and complex shaped parts can be manufactured.

 

Brief introduction of widely used metal materials for 3D printing

3D metal printing, also commonly known as metal fusion, has conquered new markets in aeronautics, medical, construction and automotive sectors in last few years with its incomparable advantages and convenience. At present, 3D printing metal technology is fast and relatively cheap, can also be used to create large structures. The printing technology mainly includes selective laser sintering (SLS), electron beam fusion (EBM), selective laser fusion (SLM) and laser engineered net shaping (LENS). SLM use a high-energy laser source which can melt a variety of metal powder, is the most commonly used method. Metal powder used for 3D printers in domestic and foreign generally are: Tool steel, Martensitic steel, Stainless steel, Pure titanium and titanium alloy, Aluminum alloy, Nickel base alloy, Copper base alloy, Cobalt-chromium alloy and so on.

 

STAINLESS STEEL

Stainless steel is the first material used in 3D metal printing due to its good chemical resistance, high-temperature resistance and good mechanical properties. At present, there are mainly three kinds of stainless steel applied in metal 3D printing: Austenite stainless steel 316L, Martensite stainless steel 15-5PH and Martensite stainless steel 17-4PH.

316L Austenitic stainless steel, with high strength and corrosion resistance, can be reduced to low temperature in a wide range of temperatures. It is applied in various engineering applications such as aerospace and petrochemical, as well as food processing and medical treatment.

15-5PH Martensitic stainless steel, also known as Martensitic aging (precipitated hardening) stainless steel, has high strength, good toughness and corrosion resistance, is a further hardening of the ferrite-free steel. At present, it is widely used in aerospace, petrochemical, chemical, food processing, paper and metal processing industries.

17-4 PH Martensitic stainless steel, which still has high strength and high toughness under 315 ℃, and strong resistance to corrosion and can bring excellent ductility as the laser machining state.

 

TITANIUM ALLOY

Titanium alloys have been widely used in aerospace, chemical industry, nuclear industry, sports equipment and medical devices due to their high temperature resistance, high corrosion resistance, high strength, low density and biocompatibility. Titanium alloy parts have been widely used in high-tech fields, such as F14, F15, F117, B2 and F22 military aircraft. The proportion of titanium used in a Boeing 747 aircraft is respectively 24%, 27%, 25%, 26% and 42%. However, the traditional forging and casting methods to produce large titanium alloy parts have many disadvantages, such as high cost, complex process, low material utilization rate and difficult follow-up processing, which hinder its wider application. Metal 3D printing technology can solve these problems fundamentally, so it has become a new technology for directly manufacturing titanium alloy parts in recent years.

TiAl6V4 (Gr5) is the first alloy used in SLM3D printing production. However, the poor plastic shear deformation resistance and wear resistance of titanium limit its use under high temperature, corrosion and wear resistance conditions. Therefore, Re and Ni are introduced into titanium alloys, and the 3D printed Re-based composite sprinkler has been successfully applied to the combustion chamber of aero-engine, and the operating temperature can reach 2200%.

 

COBALT

H13 hot work tool steel is one of them. Tool steels are widely used in industrial parts because of their excellent hardness, wear resistance, deformation resistance and the ability to maintain cutting edges at high temperatures. Martensitic steels, taking Martensite 300 as an example, also known as maraging steels, are noted for their high strength, toughness and dimensional stability during aging. Due to its high hardness and wear resistance, Martensite 300 is suitable for many die applications such as injection molds, light metal alloy casting, stamping and extrusion, and is also widely used in aerospace, high strength fuselage parts and racing car parts.

 

ALUMINUM ALLOY

Aluminum alloys have excellent physical, chemical and mechanical properties and have been widely used in many fields. However, the properties of aluminum alloys themselves (such as easy oxidation, high reflection and thermal conductivity) increase the difficulty of selective laser fusion manufacturing. There are some problems such as oxidation, residual stress, void defects and densification in SLM process when printing aluminum alloys. These problems can be improved by strictly protecting atmosphere, increasing laser power and reducing sweep speed. At present, SLM prints aluminum alloy materials mainly are the Al-Si-Mg series alloy such as AlSi12 and AlSi10Mg. Aluminum-silicon 12 is a lightweight additive manufacturing metal powder with good thermal performance. It can be applied to thin wall parts, such as heat exchangers or other auto parts. It can also be applied to the prototype and production parts of aerospace and aviation industry.The addition of silicon and magnesium gives the aluminum alloy more strength and hardness, making it suitable for thin wall and complex geometric parts, especially in the case of good thermal performance and low weight.

 

MAGNESIUM ALLOY

As the lightest structural alloy, magnesium alloy has the possibility of replacing steel and aluminum alloy in many application fields due to its special high strength and damping properties. For example, lightweight applications of magnesium alloys in automotive and aircraft components can reduce fuel use and exhaust emissions. Mg alloy has excellent in-situ degradation and biocompatibility, with low Young’s modulus and close to the human bone strength. It has more application prospect in surgical implantation than traditional alloy.

 

HIGH-TEMPERATURE ALLOY

High temperature alloy refers to the super steel alloy which with iron, nickel and cobalt as the base and can still long-term work in the high temperature of 600 ℃ or above and stress environment. It has high temperature strength, good resistance to corrosion resistance and oxidation resistance and good plasticity and toughness. At present, the alloys can be roughly divided into three categories: Fe based alloy, nickel based alloy and cobalt alloy.

Superalloy is mainly used in high-performance engines. In modern advanced aero engines, the use of superalloy material accounts for 40% ~ 60% of the total engine mass. The development of modern high performance aero engines requires more and more high temperature and performance of superalloy. The traditional metallurgical process of ingots is slow in cooling, some elements and second phase segregation are serious in ingots. 3D printing is a new method to solve the technical bottleneck in nickel alloy forming.

As a result, Inconel 625 is frequently used in metal parts used in marine applications and  oil and gas production. Inconel 718 is an age-hardened version of 625. 718 is a nickel-based alloy, which has good corrosion resistance and heat resistance, stretching, fatigue and creep properties, and is suitable for various high-end applications, such as aircraft turbine engines and land-based turbines. Inconel 718 alloy is the earliest used nickel base superalloy and is also the most used alloy of the aero engine at present.

Cobalt-chromium alloy has high strength, strong corrosion resistance, good biocompatibility and non-magnetic properties. It is mainly used in surgical implants, including alloy artificial joints, knee joints and hip joints, and can also be used in engine parts, fashion and jewelry industries.

 

Since the emergence of 3D printing technology in the 1990s, from the initial polymer materials to metal powder, many new technologies, new equipment and new materials have been developed and applied. There are a wide range of metal materials suitable for industrial 3D printing, but only several specified powder materials can meet the requirements of industrial production. Although the 3D printing technology of metal powder has achieved some achievements at present, the material is still the biggest factor and there are more higher requirements on 3D printing materials. Therefore, the development of 3D printing technology of metal powder still has a long way to go.

 

What’s 2205 steel?Duplex stainless steel S31803 or S32205?

Duplex stainless steel (UNS S31803, S32205, S32750, S32900) combines the advantages of Ferrite and Austenite steel. Its duplex structure is conducive to obtaining high strength and stress resistance. In addition, higher content of chromium, nitrogen and molybdenum increases corrosion performance and duplex steel also has good welding performance. Due to its excellent properties, duplex stainless steel is widely used in chemical industry, paper manufacturing, desalination equipment, firewalls, Bridges, pressure vessels, heat exchangers, turbine blades and transmission shafts of offshore systems.

Sometimes, UNS S31803 and UNS S32205 are referred to as duplex 2205. Generally, UNS2205 contains ASTM S31803 and S32205 duplex stainless steels. In other words, S31803 and S32205 are both called  2205 stainless steel, and S32205 is the upgraded series of S31803 by the adding of the lower limit content of Cr, Mo and N elements, which makes the little difference in mechanical properties. Their tiny differences in chemical elements and physical properties are showed below:

According to the ASTM A182 Standard, Specification for forged or stainless steel pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service, UNS S31803 and UNS S32205 cannot be confused and they specified in different number, S31803 is marked by F51 and S32205 is F60.

When speaking of 2205 steel, it generally refers to S31803 or F51, while UNS S32205 or F60 conforms to ASTM 2205 adopts its higher corrosion resistance range, that is, UNS S32205 requires higher Chromium and Nitrogen content, thus guaranteeing better corrosion resistance. Generally, S32205 steel plate and S31803 are also called double standard steel plate, or 2205 steel plate for short. Our factory produce 2205 tubing and 2205 plates to make its chemical composition conform to two specifications of UNS 31803 and S30025. Our steel plate in stock can meet two kinds of standards at the same time.

2018 China’s Titanium welded tube market outlook

 

Since the production of sponge Titanium by magnesium reduction method in the United States in 1948, we have stepped into the golden age of titanium industry. Titanium has been widely used due to its light specific gravity, high strength, low thermal conductivity, corrosion and high-temperature resistance, weldability, no magnetism, and excellent properties. Due to its high production cost, the titanium hadn’t earned the wide application in the industrial field. In recent years, with the development of science and technology and the progress of production technology, titanium can be processed into various forms and applied in many fields. Titanium has become an indispensable material in aerospace, Marine, petrochemical, medical and other industries.

Titanium pipe can be divided into seamless Ti pipe and welded Ti pipe. Now the seamless titanium tubes in Chinese market generally adopt the vacuum annealing process of cold rolling, that means, the titanium ingot is made into the tube billet through forging bar billet, and then through multi-pass rolling and annealing process, finally the seamless titanium tubes are made. In recent years, China’s titanium welding pipe factories have been put into operation successively, and the production of titanium welding pipe increases year by year. However, the main domestic pipe manufacturers are mainly still produced seamless pipe, which is the mainstream in the market of applications.

Although the processing technology of titanium seamless tubes is mature, limited by the equipment behind developed countries, titanium pipes mainly use low-strength, low-alloy pure titanium or alloy Ti-Mo-Ni and other medium and low-strength alloy titanium as the base material and the cold rolling processing technology. Medium and high strength titanium alloy pipes, such as the Ti6Al4V pipe, need hot rolling which needs to install induction heating device on the rolling machine. For the pipes with special requirements, seamless pipe production became more difficult. For those thin-walled titanium and titanium alloy pipes or for super-long titanium pipes over 14m in length. In addition, the production of seamless titanium pipe requires many tools and abrasive tools and complicated equipment, resulting in limited production capacity and long production cycle of manufacturers, which cannot meet the market demand for thin-walled pipe, ultra-long pipe and low-cost pipe.

Based on the disadvantages of the titanium seamless tube mentioned above, the titanium welded tube emerges. As a relatively unique titanium tube product, the ti-welded tube is produced by the ti-rolled coil supporting tube, which is welded by the tungsten electrode inert gas protection. The biggest international titanium welding pipe companies include Japanese steel company and KOBE steel company, France’s Valtimet company, Russia’s VSMPO company and so on. In the mid-1980s, Xi ‘an BaoMei Farino welding pipe co., Ltd. established two automatic estimated advanced welding pipe production lines, and the company became the first welding titanium pipe manufacturer in China.

Compared with titanium seamless tube, titanium welded tube can be used to make pipe fittings with a thinner wall thickness, which can reach 0.3mm-0.5mm, while the minimum wall thickness of titanium seamless tube is about 0.9mm. At the same time, the raw material utilization rate of welded pipe, production efficiency and economic efficiency is better. As titanium material has excellent corrosion resistance to seawater, titanium welding pipe has gradually replaced stainless steel and copper alloy pipe to become the preferred material for condenser and heat exchanger. Therefore, it is widely used in coastal power plant, seawater desalination, Marine oil and other condensers and heat exchangers that need seawater as a cooling medium.

In European and American countries, the welded pipe used for condenser and the exchanger in coastal power generation and nuclear power plants has gradually replaced titanium thin-walled seamless tube. There are more research had been proved that titanium welded pipe has the more excellent performances than the seamless tube in the term of joint performance, compression performance, and anti-fatigue, which shows that the welding quality of welded pipe can satisfy the use of the harsh environment. Seamless titanium pipe is insufficient in the low yield and long production cycle and high cost compared with welded pipe, especially the production of commercial pure titanium welded pipe, it will be a new trend in the long run with its short, low production cost and high production efficiency.
