Tungsten Nickel Iron Alloy Description
Tungsten nickel iron alloy is an alloy composed of tungsten as the matrix and a small amount of nickel, iron and other alloy elements. It has the characteristics of high density (18.8g / cm3) and adjustable, strong ability to absorb high-energy rays (1 / 3 higher than the ray absorption coefficient of lead), low coefficient of thermal expansion, good plasticity, high strength and elastic modulus, good machinability and weldability. So WNiFe alloy is widely used in radiation protection and guidance, industrial counterweight parts, safety and defense parts, etc

Introduction:
The density of tungsten heavy alloy is very high. Its density is twice of steel. Tungsten heavy alloy has low thermal coefficient but it has high absorption ability and high-energy rays. The tungsten heavy alloy we make conforms to ASTM B777-99 standard.
It is massively applied to balancing weight mould and high temperature moulds. Also they can be made into protective shield and high-energy rays. The tungsten heavy alloy conforms to ASTM B 777-99 standard.
