Copper Tungsten Rod

Copper Tungsten Rod

Copper tungsten rod is an alloy composed of the tungsten element and copper element, copper content in alloy is commonly occupy an amount of 10% to 50%. Preparation of alloy powder metallurgy method, has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, copper alloy is liquefied evaporated absorbs heat, reduces the surface temperature of the material. So this kind of material is also referred to as metal sweating material.

Copper Tungsten Rod Sizes:

W-Cu Rods: Dia(1.0-60)* (10-500)mm

Copper Tungsten Rod Applications

Copper Tungsten Rod is mainly used for electrical discharge machining electrode materials, electronic packaging materials, high temperature materials, sealed cap for transistors sealing welder,for making high speed steel and switches and contacts in high and low voltage electrical devices.
