Product Detailed Specification


Characteristics of Tungsten copper

Tungsten copper is a composite material made by static pressure forming, high temperature sintering and copper dissolution, which takes advantage of the excellent metal properties of high purity tungsten powder, the plasticity and high conductivity of high purity red copper powder and other advantages. Tungsten copper is good at arc breaking performance, thermal conductivity, small thermal expansion. Besides, tungsten copper is high in strength, density, and hardness. Tungsten copper does not soften in high temperature .
