Tungsten heavy alloy

Tungsten heavy alloy is a kind of alloy using tungsten as matrix and components nickel, iron, copper and other alloying elements, with the characteristics such as: high and adjustable density(~ 18.5g/cm3), good absorption ability of high-energy radiation (1/3 higher than the absorptivity of lead ray), low coefficient of thermal expansion (4 ~ 6×10-6/℃), good plasticity, high strength and elasticity modulus, machinability and weldability.

Tungsten heavy alloy is widely used in radiation shielding materials, balance weight materials, inertia materials, dynamic balance materials, kinetic energy materials, high temperature molds etc.
