Tungsten Alloy is an alloy with tungsten as the main element and added with Ni、Cu、Co、Mo、Cr and other elements. It has a series of excellent characteristics: the density is as high as 16.5-19.0 g/cm3; The specific gravity is 16.5-18.75 g/cm3. The tensile strength is 700-1000 MPa. Strong ability to absorb rays, 30-40% higher than lead; The thermal conductivity is 5 times that of die steel. The coefficient of thermal expansion is small, only 1/3-1/2 of iron or steel; Good weld ability and mach inability.

Tungsten Alloy is an alloy produced by powder metallurgy with tungsten powder as main raw material and Fe, Ni, Co as binder. It has excellent uses such as high melting point, high hardness, high strength, high specific gravity, creep resistance, thermal conductivity and electrical conductivity, and is widely used.

The climax of research on the brief history of tungsten alloy development is mainly pided into the following four stages:
