Description

CuW85 CuW90 Tungsten Copper Electrical Contacts Arc Erosion Resistance for electrical discharge machining

Tungsten Copper Electrical Contacts

Tungsten Copper Electrical Contacts are the best material for electrical discharge machining (EDM). It has excellent wear resistance, good metal removal rate and the ability to retain good detail. It is used where speed and wear resistance are the most important. Tungsten copper material not only has good thermal conductivity and low thermal expansion coefficient, but also can be designed by changing its tungsten copper content to design its thermal conductivity and thermal expansion coefficient.

We specialize in the production of medium voltage contacts of any shape and size, as well as the assembly of finished products by induction welding and machining. Tungsten-copper contact is a tungsten-copper alloy composite material, which not only has copper's excellent electrical and thermal conductivity, while tungsten has high density, high strength, high melting point and low expansion coefficient, tungsten-copper has excellent heat resistance, Aberration resistance, high density, excellent thermal and electrical conductivity. Neither can form immiscible intermetallic compounds. Tungsten copper contacts are the best material for electrical discharge machining (EDM)

Tungsten Copper alloy Properties:

Tungsten-copper alloy features good heat and electrical conductive, high temperature resistance strength and ductility.

Tungsten copper alloy applications:
Tungsten copper alloy has wide applications. Tungsten copper alloy is widely used to manufacture switch contact for high-voltage electrical appliances, rocket nozzle throat liner and sternpost rudder, and other high temperature components and parts. In addition, it also can be used to make electrode for spark processing, high temperature mold and other high heat and electrical conductive parts. And also WCu alloy can be applied as electrodes for electrical machining.
