What is Wolfram Heavy Alloy?
Wolfram heavy alloy also called wolfram alloy is refractory metal, which consists of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe. Wolfram heavy alloy materials satisfy the most stringent requirements of manufacturing industries. Wolfram alloy could be made as various shapes, such as wolfram alloy rod, wolfram alloy cube, wolfram alloy block, wolfram alloy brick, wolfram alloy ring, wolfram alloy sheet,etc.
Wolfram heavy alloy has so many properties, such as high density, high melting point, small volume, superior wearing resistance, well machinablity, high radiation absorption capability, good shock resistance, etc. The table shows you typical properties of wolfram alloy.

Due to the properties of wolfram heavy alloy, wolfram alloy can be widely used in many areas.
Wolfram is up to 65% denser than lead and 130% denser than steel. Based on its very high density where it is used to control or distribute weight in some way, wolfram alloy could be manufactured as counterweight such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, golf club weights, etc.
Since its high radiation absorption capability, radiation shielding is a second common application of wolfram heavy alloy used both in medical and industry. Wolfram alloy also could be manufactured as the parts of military defense, vibrators, engine components, fisher sinkers, extrusion die, etc. We can provide all kinds of wolfram heavy alloy products according to your requirements.
