Product Description
Tungsten heavy alloy Cubes 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 cube is in small volume with high density, which means it could be used in some fields need the little but heavy parts.

Usually tungsten alloy block could be manufactured as the parts of military defense, extrusion die, some counterweights, such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc . Also tungsten alloy block is now widely used in manufacturing parts concerning medical field, such as radiation shielding wall, block for CT facility, etc
