Since the melting point and boiling point of copper are much lower than the melting point and boiling point of tungsten, the tungsten-copper material can take a lot of heat through the “sweating” effect of copper under the high temperature of the arc, so that the tungsten skeleton cools and maintains good mechanical properties. To ensure the breaking ding of the electrical contacts. Therefore, the good anti-corrosion, anti-welding and withstand voltage characteristics of tungsten-copper materials are currently particularly suitable for…

Tungsten copper alloy is used as a nozzle for missiles and rocket engines in aerospace, gas rudder, air rudder and nose cone. The main requirement is to require high temperature resistance (3000K~5000K) and high temperature airflow scouring ability, mainly using copper at high temperature. The sweating and cooling effect of the volatilization (copper melting point 1083 ° C) reduces the surface temperature of the tungsten copper and ensures the use under high temperature extreme conditions.

The degree of surface erosion of a pulsed arc tungsten copper electrode is related to the amount or energy of the pulsed arc. For tungsten copper materials, the main form of electrode erosion is evaporation of the electrode material. The effect of pulsed arc on tungsten-copper material is positively correlated with the amount of single-pulse charge transfer and the total pulse charge transfer.

Resistance welding is a process in which a contact resistance is generated when a current is passed through a workpiece, and welding is performed under external pressure. An electrode for holding a workpiece to be welded, passing a required current and transmitting an external pressure is called a resistance welding electrode. The tungsten-copper resistance welding electrode has good electrical conductivity, high temperature hardness and strength, and does not chemically react or adhere to the material to be welded.

Tungsten copper electrode material should have stable EDM process, high productivity, good surface quality of the workpiece, and the electrode material itself should be rich in source and low in price. In the tungsten copper composite, tungsten can form a poorly soluble framework, which makes the material resistant to electrical isolation, wear and high temperature, while copper has excellent conductivity.
