Tungsten-copper alloy (WCu) is a composite material that combines the advantages of both tungsten and copper. Below are some of its basic properties:
1. High Density:
2. High Melting Point:
3. Electrical Conductivity:
4. Thermal Conductivity:
5. Low Coefficient of Thermal Expansion:
6. High Strength and Wear Resistance:
7. Good Machinability:
8. Corrosion Resistance:
