Attribute：
Tungsten Heavy Alloys are materials with a high tungsten content and low amounts of Ni, Fe or Ni, Cu. Some tungsten alloy is added Co, Mo or Cr etc. Their densities could be as high as 16.8~18.8g/cc.
Advantage:
1.High density;
2.Good machinability;
3.Good mechanical properties;
4.High modulus of elasticity;
5.High absorption capacity against χ-rays and γ-rays;
6.Harmless to the health and environment.
Parameter：
Product Standard: ASTM B 777-07
We offers two series of Tungsten Heavy Alloys: W-Ni-Fe(magnetic) and W-Ni-Cu(nonmagnetic)
