Corrosion Resistance Tungsten Heavy Alloy
Heavy Tungsten Alloy Parts are made of tungsten matrix (tungsten content is generally 80% ~ 98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of high specific gravity tungsten alloy is as high as 15.20 ~ 18.70g/cm3, which is also called high specific gravity tungsten alloy or high density alloy material. Because tungsten alloy weighs more than twice as much as steel.
The density of tungsten heavy alloy parts is 16.7g/cm3 ~ 18.8g/cm3. In addition, tungsten heavy alloy parts have the characteristics of high temperature resistance and corrosion resistance. Tungsten heavy alloy parts have good impact resistance and mechanical plasticity. Tungsten heavy alloy parts have low thermal expansion coefficient and can absorb high-energy rays.CIFICATIONS & CHEMICAL COMPOSITIONS (NOMINALS)

Heavy Tungsten Alloy Parts Picture:
Tungsten alloy has a series of excellent properties, high specific gravity: General specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption capacity: 30-40% higher than general lead specific gravity, high thermal conductivity: 5 times that of die steel; Low coefficient of thermal expansion: only 1 / 2-1 / 3 of the capacity of steel, good conductivity, good weldability and machinability.
A common method for preparing heavy tungsten alloys is to mix the required amount of tungsten, iron, nickel or copper powder, and then carry out cold pressing and liquid phase sintering to near full density. In the process of liquid phase treatment, the matrix tungsten alloy melts and causes some tungsten to enter the solution to form microstructure and large tungsten particles (20-60 μ m) The microstructure is dispersed in the matrix alloy.
In order to increase the kinetic energy of the core and enhance the armor piercing ability, the application of high specific gravity tungsten alloy is a successful technical measure in the design and development of shell piercing shells abroad. At present, in addition to the United States, many Western European countries have adopted tungsten alloy core materials.
