Characteristics and features
The Copper tungsten material products are highly resistant to heat, electric arc, wear and deformation at high temperature welding, flash butt and spot welding.  They also have excellent electrical and thermal conductivity.

1. Low thermal expansion
2. High wear resistance
3. Low consumption
4. High arc resistance
5. High thermal and electrical conductivity

Application
Due to their unique properties, tungsten based composites are widely used where the combination of goods electrical and thermal conductivity and low thermal deformation is required.  Their mechanical and physical properties make them particularly suitable in electric resistance welding as electrical contacts or heat sinks and in electrodes for electrical discharge machining (EDM) and electrochemical machining (ECM)






Xi'an Kefeng Powder Metallurgy can produce below grades of Copper Tungsten metal composite materials
To meet your specific needs.  Kefeng can supply various sizes and compositions for a timely 15-30 days
Shipping or we can offer custom grades, shapes and finished parts with a short lead time.  These metal composite materials produce dense hard metals with low thermal expansion, good thermal and electrical conductivity, excellent arc resistance, superior wear resistance and strength at elevated temperatures.
