70% Tungsten, 30% Copper (WCu) Tungsten Copper Sheet - Online Catalogue Source Wolfram Copper Sheet Customized
Tungsten Copper Sheet, copper tungsten plate, block and bar are very popular used as EDM electrode. This material has both tungsten and copper's characters, for example: copper is good for electrical conductivity, tungsten is good for the hardness. Copper tungsten plate for EDM is made by vacuum infiltration technology, which has very good physical and mechanical properties.
Features:
1. High hardness, high density, high strength, high heat resistant.
2. Excellent thermal and electrical conductivity.
3. Better arc burning loss resistance, erosion resistance.
4. Easy to be machined.
