4 commonly used welding methods for titanium alloy

  Titanium offers an amazing corrosion resistance but is two times lighter than steel. Titanium also has a very high tendency to oxidize at higher temperatures. It extremely important to keep the molten metal away from atmospheric air while welding because even very little contamination of oxygen will lead to porosity. With the wide application […]

Application of titanium alloy in aviation industry

  In the 1950s, the United States developed firstly the titanium alloy Ti-13V-11Cr-3Al in high-speed awacs, making this light-weight, high-strength, heat-treatable alloy was used for flight. In the 1960s, titanium alloy was widely used in non-military aviation engines and wide-body jets such as Boeing 747s. In the 1970s, the application of titanium alloy in aviation […]

2205 duplex stainless steel welding analysis

  Composed by close to 1:1 Ferrite and Austenite phase, duplex stainless steel has excellent mechanical properties and resistance to chloride stress corrosion performance, was widely used in the oil and gas pipelines, chemical transportation tank, and the shipbuilding industry. Duplex stainless steel has excellent weldability and during the welding process, the microstructure of welding joint, especially the thermal zone, will […]

A brief introduction of two-sides titanium clad plate

  Clad titanium plate refers to the composite plates made by cladding titanium plate and base steel plate through the explosion and rolling process. The base metal usually uses some cheaper material such as carbon steel or low alloy steel plate and the cladding layer usually using the stainless steel plate and other alloy steel […]

A brief introduction of heat treatment for titanium and titanium alloy

  Titanium and titanium alloy has a perfect strength and weight ratio, good toughness and corrosion resistance. Titanium alloy is mainly used for manufacturing aircraft engine compressor parts and structural parts of missile and high-speed aircraft. In the mid-1960s, titanium and its alloys were used in the general industry to make electrodes for the electrolytic industry, condensers for power stations, heaters for […]

How many types of annealing heat treatment did you know?

  Annealing is a heat treatment process by which the steel and alloys are heated to a suitable temperature for a certain period of time and then allowing it slowly cooled (furnace cooling). The purpose of annealing is to transform steel from Austenite to Pearlite, reduce hardness and increase ductility, facilitate machining and cold deformation, and at the same time uniform […]

What’s CP titanium?

Titanium is classified into two categories according to the content of titanium and other impurity composition such as aluminum (Al) and vanadium (V): Commercially pure titanium (CP Titanium) and titanium alloys. CP titanium provides corrosion resistance, strength and fatigue characteristics that compare favorably to those of nickel and steel alloys. CP titanium is widely used […]

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 […]

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 […]

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 […]
