Tungsten Copper Bar Picture
W85 tungsten copper bar manufactured by PM (Powder Metallurgy) and has excellent thermal, electrical conductivity, high-temperature strength and plasticity, which is a kind of heat sink materials. In addition, it should be noticed that adjust the parameters when tungsten copper discharging or wire cutting, and the speed is lower than other materials.
