W70Cu30 W75Cu25 Copper WCu Alloy Dics Ring For ECM Electrodes
W70Cu30, W75Cu25 Tungsten And Copper WCu Dics And Ring
Product Description
Tungsten-copper alloy is an alloy composed of tungsten and copper. The copper content of common alloys is 10%~50%. The alloy is made by powder metallurgy and has good conductivity and thermal conductivity, high-temperature strength and certain plasticity. At very high temperatures, such as above 3000 ℃, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. So this kind of material is also called metal sweating material.
Application
1. EDM (Electrical Discharge Machining) electrodes;
2. ECM (Electrochemical Machining) electrodes;
3. Machining other parts, toy and so on;
4. Industries as engine,electric power, electron,metallurgy,spaceflight and aviation.
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.
