Our Heavy Tungsten Alloy Products are generally refractory metals, which have W-Ni-Fe or W-Ni-Cu or even W-Ni-Cu-Fe two-phase composite materials. Its melting point is very high, its density is twice that of steel, and it is more than 50% heavier than lead. The tungsten content of heavy tungsten alloy is 85-99%. With nickel-iron or nickel-copper as binder, its density can reach 16.5-18.89 g/cm3. Heavy tungsten alloy has the advantages of ray density (more than 60% of lead density), corrosion resistance, good machinability, high radiation absorption (better than lead), and high strength. It is a suitable raw material for radiation protection.
