Products Description
CuW alloy is an excellent high-temperature-resistant material.It is mainly made of high-quality tungsten powder and oxygen-free copper powder through isostatic pressing. It is made after high-temperature sintering and copper infiltration. It has high strength, high temperature resistance, milk arc ablation, good processing performance, good thermal and electrical conductivity, fine internal structure and other characteristics.
Copper Tungsten Sheets can be widely used as electrical contact material, electrical processing material, electrode material or instantaneous high temperature material, and it can also exert excellent performance in high temperature, high pressure and high corrosion environment.
Copper Tungsten Sheets are mainly used in medium and high voltage and medium and high current switching appliances. Copper Tungsten Sheet is often used as an instantaneous high-temperature material to manufacture high-temperature components of spacecraft, which can protect important components from ablation of high-temperature solid particles.
features of Copper Tungsten Sheets
1. High density and thermal conductivity: The density (14-17g/cm³) and thermal conductivity (180-220W/(m·K)) are adjustable, suitable for thermal management scenarios.
2. Corrosion resistance and oxidation resistance: After Ni/Au is plating on the surface, the corrosion rate is reduced and the service life is extended in a high-temperature oxidation atmosphere.
3. Processability and gradient components: moderate hardness, can be processed into complex shapes, and the gradient design of components takes into account both strength and thermal conductivity.

application of Copper Tungsten Sheets
1. Copper tungsten sheet is used for high-power pulse microwave tubes, laser diodes, and integrated circuit module heat sinks, and the thermal resistance is reduced.
2. Copper tungsten sheet is used in high-voltage, oil-free, less oil circuit breakers, SF6 circuit breakers, etc., and has excellent arc ablation resistance.
3. Copper tungsten sheet is used for nuclear reactor control rods and rocket engine nozzle throat linings, which withstand high temperatures and strong radiation.
