Tungsten Copper Alloy Block Ring Rod with high Arc Resistance and good Thermal Property
Material Property
With the 6~50% copper(by weight), the W-Cu alloy has integrated both advantages of tungsten and copper. Characterized by good high temperature resistance, arc ablation resistance, thermal and electrical conductivity , high strength, machining-ease, and outstanding sweat cooling ability and specific gravity ,it is widely applied in machinery, electric power, electronics, metallurgy, aerospace and other industries.
Application
Tungsten Copper composite materials are widely used in:
− Switches or circuit breakers of arc contact and vacuum contact in medium-high voltage application
− Electrodes used for EDM
− High- temperature -resistance materials
− Heat spreader on electronic equipment
−− Microwave, laser, radio frequency (rf), optical communication and other high power devices
−− Lead frame of the high performance
−− Thermal controlling panel and dissipation devices of military and civilian use
