Ti6Al4V ELI, UNS R56407, Grade 23

Ti-6Al-4V-ELI, UNS R56407, Grade 23 (ELI=Extra Low Interstitials) INTRODUCTION Ti-6Al-4V-ELI, Grade 23 alloy (Extra Low Interstitials, UNS R56407) is a higher purity grade of Ti-6Al-4V alloy. This grade has lower oxygen, carbon, and iron content. It is used in biomedical applications such as surgical instruments, orthopedic implants, and is the preferred grade for marine and […]

Why ammonia corrosion are common for copper and its alloys?

Ammonia is an important raw material for the manufacture of nitric acid, ammonium salt and amine. Ammonia is gas at room temperature and can be liquefied under pressure. Most metals such as stainless steel, aluminum, magnesium, titanium, etc. have excellent corrosion resistance to ammonia gas, liquid ammonia and ammonia water, except copper and other copper […]

Heat treatment of Beryllium Copper C17200

The heat treatment of Cu-Be alloy is mainly solid solution annealing and aging hardening. Unlike other copper alloys whose strength is obtained only by cold machining, wrought copper beryllium is obtained by cold machining and hot aging hardening processes up to 1250-1500 Mpa. Aging hardening is often referred to as precipitation hardening or heat treatment. […]

Can copper and steel be welded together?

As we all know, copper and steel (iron) are two different metals. The thermal conductivity of copper is 7-11 times greater than that of ordinary carbon steel, and it is difficult to reach the melting temperature. When copper is melted, its surface tension is 1/3 less than that of iron, and its fluidity is 1-1.5 […]

The bright annealing process of copper alloy strip and wire

The common heat treatment methods of copper alloy are homogeneous annealing, stress – free annealing, recrystallization annealing, solid solution and aging treatment. In order to prevent oxidation during processing, save the cost of pickling and obtain a bright surface, it is allowed to anneal copper alloy strip, wire and coil tube in a protective atmosphere […]

What’s beryllium copper used for?

In last article, we discussed the question”What’s Beryllium Copper”, as well as we know, Beryllium Copper is also known as beryllium bronze, is a type of precipitated hardened copper alloy with beryllium as the main alloying element. Its density is 8.3g/cm³, 0.2~2.75% beryllium making its strength is twice that of other copper alloys. Beryllium copper […]

Carbide VS HSS drill bit

A drill bit is a cutting tool with circular cross-section that create holes in an alloy materials. The commonly used drill bits mainly include spiral bit, flat bit, center bit, deep hole bit and bush bit. Reaming and countersink drill bits may not be used to drill holes in solid material, but they are traditionally […]
