W70 Tungsten copper alloy rods Electrode for high voltage discharge tube
product description
Luoyang Achemetial Tungsten&molybdenum Co., Ltd. adopts high purity tungsten powder and oxygen-free copper, through sintering, melting and other processes, fine production of various tungsten and copper products. The tungsten and copper bars produced by our company have the characteristics of uniform organization, precise composition ratio and high processing accuracy. Luoyang Achemetal Tundsten&molybdenum Co., Ltd. production of tungsten and copper rods can withstand high temperature, arc ablation, high strength,good thermal conductivity and conductivity, is a good sweating cooling material, our tungsten and copper rods can be widely used in aerospace, electric power,electronics,metallurgy, machinery, and other fields in the production.
Application
1. Resistance welding electrode.
It has the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, high specific gravity, good electrical and thermal conductivity, easy cutting and processing, and has the characteristics of sweating and cooling, etc. Because of the high hardness of tungsten, high melting point, anti-adhesion characteristics, it is often used as a certain wear resistance, high temperature resistance convex welding, butt welding electrode.
2. High voltage discharge tube electrode.
When the high-voltage vacuum discharge tube is working, the temperature of the contact material will rise several thousand degrees Celsius in a fraction of a second, while the ablation resistance, high toughness, good electrical and thermal conductivity of tungsten copper provide the necessary conditions for the stable work of the discharge tube.
3,High performance materials for aerospace
Tungsten copper material has high density, sweating cooling performance, high temperature strength and resistance to scouring and ablation, etc. It is used in the aerospace industry as nozzle lining of missiles and rockets, components of gas rudder, air rudder, cowl and counterweight, etc.
4,Vacuum contact material
Contact material must have very good mechanical processing properties and thermal shock resistance, due to the contact and open arc, contact material will be in the fraction of a few seconds of time the temperature rises thousands of degrees C. W-Cu contact material is widely used because of its excellent physical properties.
Advantages of tungsten copper alloy: high ablation resistance, high toughness, good electrical and thermal conductivity. Good machinability.
