Introduction of Tungsten Alloy rings

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, cube, block, brick, ring, etc.

1. Diameter: 5.0mm-200.0mm

2. High: 2.0mm-50mm

3. Density: 15.8-18.75 g/cm3

4. Composition: W content: 85-97%, W-Ni-Fe, W-Ni-Cu

5. Surface: Sinter state, Grind state

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 ring

Tungsten alloy ring is mainly used for sealed cap for transistors sealing welder, contactor materials for high voltage switches and electrodes for spark processing etc.

Military industry: penetrating projectiles, counterweights for military defense, projectiles in the missile weapons, armor piercing ammunition, prefabricated fragments.
