Copper alloy plate made of tungsten (W80Cu) for contact purposes
1. W80Cu Tungsten Copper Alloy Plate For Contact Material Specifications:
W80 and W85 tungsten copper plates are the most popular types of tungsten copper alloy plate. Spark electrodes frequently employ tungsten-copper alloy plates. The electrical and thermal conductivity of copper and the high hardness and arc ablation resistance of tungsten are both present in tungsten-copper alloys. In order to give tungsten copper alloy plates their good physical and chemical qualities, vacuum sintering is typically utilized in the manufacturing of electric spark.
2. Common size of W80Cu Tungsten Copper Alloy Plate For Contact Material:
| Thickness (mm) | Width (mm) | Length (mm) |
| 2-50 | 100 | 100 |
| 100 | 200 | |
| 200 | 300 |
3. Physical index of W80Cu Tungsten Copper Alloy Plate For Contact Material:
| Grade | Density (g/cm3) | Thermal conductivity | Thermal expansion coefficient |
| WCu10 | 17.0 | 160 | 6.2 |
| WCu15 | 16.2 | 170 | 6.9 |
| WCu20 | 15.4 | 180 | 7.4 |

4. Application of W80Cu Tungsten Copper Alloy Plate For Contact Material:
1). Electrode material: Pu-chip electrodes and high hardness materials are used for EDM with this material. The surface finish, precision, loss, and cost-effectiveness of EDM goods are all quite high.
2). Contact materials, including circuit board welding, electrical contact points, and arc and vacuum contacts of high- and medium-voltage switches or circuit breakers.
3). Materials for welding include submerged arc welding equipment, gas shielded welding tips, and radio resistance factories (production of carbon film resistance, metal coating resistance) resistance machine for butt welding butt welding material(copper tungsten alloy welding disc).
4). All forms of wire-rolled steel are employed as guides and protectors of materials.
