Tungsten Cubes (WNiFe, WNiCu alloy) according to standard ASTM B777 , AMS- T 21014 , density HD 17 , HD 17BB , HD 17D , HD 17.5 , HD17.7 , HD 18 , HD 18D , HD 18.5 g/cm3 , including 90WNiFe, 93WNiFe , 95WNiFe , 97WNiFe , 90WNiCu, 93WNiCu , 95WNiCu , 97WNiCu etc.
Tungsten alloy cubes are produced by high density tungsten alloy such as WNiFe and WNiCu . characteristic : high density, good compressive strength, oxidation resistance, good electrical conductivity, thermal conductivity and corrosion resistance and high density (density from 16 g/cm3 to 18.5 g/cm3). ), much higher than nickel, titanium, lead. Tungsten alloy blocks also have good tensile strength, expansion coefficient and large elastic modulus. Used in the military as a piercing projectile core filling material and various weight parts.
