Tungsten Copper Alloy Contact

Tungsten Copper Alloy Contact are the key method of vacuum infiltration is used for contact and diffusion. The material after it is made can absorb a large amount of heat in the arc. High compressive strength, arc corrosion resistance, significantly improved electrical and thermal conductivity, and reduced galvanic action. Tungsten Copper Alloy Contact is a pseudo-two-phase alloy composed of Cu and W. It is made by pressing, sintering and infiltrating a carefully prepared powder mixture. It has the high density, low expansion characteristics and corrosion resistance of tungsten. Strong, excellent wear resistance and metal removal rate, and high electrical conductivity and high heat resistance of copper.

1. Outstanding arc resistance: Tungsten can effectively resist the high temperature erosion of the arc due to its high melting point which lessens contact burning and, enhances service life.

2. Good thermal conductivity: The addition of copper bestows the contact with good thermal conductivity. This allows current to be conducted quickly, decreases resistance, energy loss, heat generation, and most importantly, dissipate the generated heat in time to prevent equipment failure from overheating.

3. Excellent mechanical properties: high hardness and strength, able to endure certain mechanical shocks and vibrations while maintaining the structure stability during electrical equipment operations and ensuring dependable connections.

Tungsten Copper Alloy Contact is the best material for electrical discharge machining (EDM) applications, often found in circuit breakers, signal contactors, and electrical transfer switches in high and medium voltage environments. It should be noted that in the application equipment, the content of tungsten and copper can be adjusted appropriately according to the actual situation in order to exert the best performance of the electrical contact.
