Tungsten Heavy Alloy Description
Tungsten heavy alloys (WNiFe and WNiCu) with high specific gravity are called 3 high (or 3H) alloys, i.e. alloys with high density, high strength and high hardness. Therefore, one important use of tungsten heavy alloys with high specific gravity is widely used as counterweight.

Tungsten Heavy Alloys Properties
Tungsten heavy alloys have good weldability and processability.
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.
