Heavy alloy

Tungsten heavy alloy has a tungsten content of between 85 and 98.5 % by weight. The rest is either a soft-magnetic *¹ nickel/iron or non-magnetic *² nickel/copper additive. Tungsten heavy alloys are characterized by high densities of 17 to 18.5 g/cm³ as well as high strength and ductility.

Tungsten heavy alloy has a good machinability compared to chemically pure tungsten. The material can lathed, milled and drilled using tungsten-carbide tools in the K10 range - threading is also possible. Consequently, even complicated components can be produced on the basis of customer drawings.
