Tungsten-copper parts are made from high-performance tungsten-copper alloy, combining tungsten’s high melting point and strength with copper’s excellent electrical and thermal conductivity. 

Tungsten-copper heat sinks are composite materials that combine high thermal conductivity with a low coefficient of thermal expansion. 

Silver tungsten rod is a high-performance metal composite material composed of 60% tungsten and 40% silver.
