Tungsten Copper Alloy Contact
Tungsten Copper Alloy Contact Features
Generally, the 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.
Application
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.
