High specific gravity alloy is a tungsten matrix, and add a small amount of Ni, Fe, Mn, Co.Cu, Mo, Cr and other elements of the alloy, with high density, high strength, high hardness, good ductility, good electrical and thermal conductivity and other excellent properties; Its density can reach 15.5~18.70g/cm3. We have rich experience in the ratio of raw materials and production process in alloy, and can customize tungsten alloy products with complex shapes according to customer requirements.
