Tungsten copper alloy tube is an alloy composed of tungsten and copper. The copper content of commonly used alloys is 10% to 50%. The alloy is prepared by powder metallurgy and has good electrical and thermal conductivity, good high-temperature strength and certain plasticity. Therefore, tungsten copper alloy tubes are very versatile.
1. Resistance welding electrode: It combines the advantages of tungsten and copper. It is resistant to high temperatures, arc ablation, high strength, heavy specific gravity, good electrical and thermal conductivity, easy to cut and process, and has the characteristics of sweating and cooling. Due to the properties of tungsten Characterized by high hardness, high melting point, and anti-adhesion, tungsten-copper alloy tubes are often used to make projection welding and butt welding electrodes with certain wear resistance and high temperature resistance.
2. Electric spark electrode: When molds made of tungsten steel and high-temperature-resistant superhard alloys need to be electrically corroded, ordinary electrodes have large losses and are slow, while tungsten copper has a high electrical corrosion rate, low loss rate, and precise electrode shape. Excellent processing performance, tungsten copper alloy tube can ensure that the accuracy of the processed parts is greatly improved.
3. High-voltage discharge tube electrode: When the high-voltage vacuum discharge tube is working, the temperature of the contact material will rise by several thousand degrees Celsius in a few tenths of a second. However, the tungsten-copper alloy tube has excellent ablation resistance, high toughness, and good conductivity. , Thermal conductivity provides necessary conditions for the stable operation of the discharge tube.
