Use of tungsten alloy: it is widely used in high-temperature resistant materials, electrical alloys for high-voltage switches, EDM electrodes and Microelectronic Materials. As parts and components, it is widely used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries. Tungsten material has good welding and corrosion resistance, so it is widely used in industrial and domestic circuit breakers.
Various types of tungsten provide higher with higher conductivity, and higher tungsten makes it have greater corrosion and welding properties. Tungsten materials are made of high tungsten content, which burns out the contacts for large low-voltage circuit breakers, and carries a stable line current molded case circuit breaker contact and various equipment for maintaining circuit breakers.
These contacts can also be used for high current contact resistance contact welding and arc corrosion. Tungsten electrode is generally used for AC welding of aluminum and magnesium alloys. Tungsten alloy tungsten alloy has high hardness and strong ability to resist arc corrosion, adhesion and fusion welding. Made by powder metallurgy. It is used as the pre contact of low-voltage power switch, lifting switch, locomotive switch and high current switch, as well as heavy load relay, air circuit breaker, etc.
Adding cobalt can improve the wettability to tungsten and reduce the contact resistance. Different tungsten alloys have different properties, but also have the characteristics of high melting point, high hardness, good arc corrosion resistance, welding performance and low data transfer. The characteristic of tungsten is its fierce resistance to high current arc.
