Tungsten Copper Plate

tungsten-copper-plate

General information

Tungsten-copper alloy plate combines the advantages of tungsten and copper. Tungsten with high melting point (the melting point of tungsten is 3410 ° C, the melting point of copper is 1080 ° C), and the density is high (tungsten density is 19.25 g/cm, copper density is 8.92/cm3). Copper with excellent electrical and thermal conductivity. Tungsten-copper alloy (commonly composed of WCu7~WCu50) with uniform microstructure, high temperature resistance, high strength, arc erosion resistance and high density. It with moderate conductivity and thermal conductivity and is widely used in military high temperature resistant materials. , high-voltage switch with electrical alloys, electrical processing electrodes, microelectronic materials, as parts and components are widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.

Properties

Tungsten-copper alloy (the composition generally ranges from WCu7~WCu50) with uniform microstructure, high temperature resistance, high strength, arc erosion resistance and high density; moderate conductivity and thermal conductivity

Tungsten copper plate application

1. Electrode material: It is applied to high-hardness materials and electric discharge machining of cymbal electrodes. The surface of electro-processed products has high surface finish, high precision, low loss.

2. Contact material: arc contact and vacuum contact of high and medium voltage switch or circuit breaker, circuit board soldering and electrical contact point.

3. Welding materials: submerged arc welding machine, gas shielded welding machine welding tip, radio resistance factory (production of carbon film resistor, metal coating resistor) resistance butt welding machine (copper tungsten alloy welding disc).

4. Guide material: various wire rolling, used for guiding protective materials
