W85Cu15 Copper Tungsten Electrical Contacts With High Heat Resistance

Tungsten Copper  Electrical contact W85Cu15

Tungsten copper alloys 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. WCualloys are also used in electrodes for electrical discharge machining and electrochemical machining.

Advantages

Higer thermal conductivity

Low thermal expansion

High arc resistance combined with good electrical conductivity

Applications

1.Resistance Welding
The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make tungsten copper alloy very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.

2.Electrical Contacts
Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Our tungsten copper materials are used owing to their unique physical properties.

3. Electrodes for Spark Erosion
Our WCu electrodes are best suitable for EDM machining of those materials.
Types of product: rods, tubes and plates
