Product Description
Introduction of Tungsten Alloy Balls (sphere)
Tungsten heavy alloys are usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co, Mo, Cr, etc. It could be made as many shapes. Tungsten alloy ball is in small volume with high density, which means it could be used in some fields need the little but heavy parts
- Diameter: 1.0mm-200mm
- Density: 17.0-18.50 g/cm3
- Composition: W content: 85-97%, W-Ni-Fe, W-Ni-Cu
- Surface: Sinter state, Grind state
- Product Standard: ASTM B 777-15
The main performance of the tungsten alloy
- High density;
- Good machinability;
- Good mechanical properties;
- High modulus of elasticity;
- High absorption capacity against χ-rays and γ-rays;
- Harmless to the health and environment.
Appliance of tungsten heavy alloy balls (sphere)
- Used as the shot of shotgun, hunting sphere,non-toxic hunting pellets
- Used as the parts for prefabricated fragments
- Used as armor piercing ammunition
- Used as Counter Weight for fishing
- Used as ballast for motorboat, sailboat, submarine
- Used as Kinetic energy penetrators for defeating heavy armor
