Customized Tungsten Copper Alloy Copper Tungsten Components For Electricity
Tungsten copper components are used where the combination of high heat resistance, high electrical and/or thermal conductivity, and low thermal expansion are needed. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As contact material the alloy is resistant to erosion by electric arc. WCu components are also used in electrodes for electrical discharge machining and electrochemical machining.
The high electrical and thermal conductivity of copper are combined with the arc-resistant and non-welding properties of tungsten or their carbides to form an extensive series of compositions.
Each tungsten copper component is designed to give the best performance for your particular application.
Description of Tungsten Copper Alloy Components:
1) Materials: W60Cu, W70Cu, W80Cu, W90Cu or Other grades as per your requests
2) Technique: infiltering method
3) Density: 15.5 ~ 18.0 g/cm3
4) Shape: Plate, sheet, strip, tube, rod, or machined parts
5) Standard: ISO9001:2008, ASTM B702
All of our Tungsten Copper alloy components are produced by the press, sinter, and infiltrate process. Each manufacturing step, including the basic powder, is closely controlled, monitored, and signed off on by Quality Assurance. After completion, all manufactured lots are checked for conductivity, density, and hardness prior to shipping. This information is recorded and kept on file, and also accompanies the parts or materials when requested.
