Tungsten alloy materials

Tungsten heavy alloy(WNiFe, WNiCu)

Tungsten alloy generally are refractory metal, which 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. It could be made as various shapes, such as rod, cube, block, brick, ring, etc.

Usually, Tungsten alloy could be manufactured as the parts of military defense, radiation shielding, extrusion die, some counterweights, such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc.

The advantage of tungsten alloy

Ability to absorb the rays: The ability is so strong that it’s about 30-40% higher than lead;
High Thermal conductivity coefficient: 5 times that of die steel;
Low Thermal expansion coefficient: Only 1/2-1/3 of that of iron or steel;
With good weld-ability and process-ability.
