Application

Copper Tungsten Electrode for Walter, Vollmer Machine,Copper tungsten electrical contacts.Kefeng's pure tungsten sheets and plates with ASTM B760 usually are used to processing the parts of shielding, target and partition to avoid the radiation.  It can be found in areas of aerospace parts, medical, oil and gas and other high technology fields.

Besides,copper tungsten alloy is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity. 

Tungsten copper alloy is used to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made out of
tungsten copper alloy. 

This copper alloy product is also made into sheet metal, tubing and plate metal.  Copper tungsten alloy is used
to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches

For the application of the Spark Erosion (EDM) process calls for copper tungsten. Usually this process is used
with graphite, but tungsten has a high melting point. This allows the copper tungsten electrodes to have a longer
service life than the graphite electrodes. This is crucial when the electrode has been processed with complex
machining.  These properties also let the rods and tubes manufactured for spark erosion be made smaller in
diameter and have a longer length since the material is less likely to chip and warp.
