Tungsten Heavy Alloy Cube
Introduction of tungsten alloy cube
Tungsten alloys generally have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co,Mo,Cr, etc . Tungsten content in conventional heavy alloys varies from 85 to 97 weight percent and is the reason for their high density, the density between 16.5 and 18.5 g/cc. It could be made as various shapes, such as rod, ball, cylinder, brick, ring, etc.
1. Diameter: 3.0mm-100.0mm
2. Density: 15.8-18.50 g/cm3
3. Composition: W content: 85-97%, W-Ni-Fe, W-Ni-Cu
4. Surface: Sinter state, finish state
5. Application: balance weight, Military industry
The main performance of the tungsten alloy
As tungsten alloy cubes are high density with small capacity, high temperature resistance, high impact resistance and crack resistance, wonderful shock resistance, good corrosion resistance, High absorption capacity against X-rays and gamma rays, Good modulus of elasticity, High hardness, etc.
Appliance of tungsten heavy alloy cubes
Tungsten alloy cubes is in small volume with high density, which means it could be used in some fields need the little but heavy parts, such as the counterweights of golf club, Pinewood Derby car, aircraft, helicopter, vehicle, boat and yacht;
Especially in precision instrument fields, such as mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights, etc.
