WCu Alloy Contact

WCu Alloy Contact Description

WCu Alloy Contact is a kind of electrical contact based on tungsten material and copper as auxiliary material. It is a pseudo-alloy product composed of two metal elements. From the perspective of physical and chemical properties, WCu Alloy Contact combines the excellent properties of tungsten and copper, such as high melting point, good plasticity, low thermal expansion coefficient, strong corrosion resistance, good high temperature resistance, high thermal and electrical conductivity,arc burning resistance and long service life, etc. And the higher the copper content, the more electrically and thermally conductive the contact will be. Tungsten has the highest strength and melting temperature among refractory metals, which are the main factors determining the resistance of contacts to arc erosion and mechanical wear. As the tungsten content increases, the strength, erosion characteristics and welding characteristics of the contact body increase.WCu Alloy Contact is mainly used in high-voltage circuit breakers, vacuum circuit breakers, ultra-hydraulic switches and other high-current switching appliances. In actual 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.
