At very high temperatures, such as Copper Tape For Power Cable above 3000°C, the copper in the alloy is liquefied and transpired, absorbing a lot of heat and lowering the surface temperature of the material.The fullway-copper alloy (composition is generally WCu7~WCu50) has a uniform microscopic arrangement, high temperature resistance, high strength, arc ablation resistance, and high density.
The alloy is made by powder metallurgy, has good electrical and thermal conductivity, good high temperature strength and certain plasticity. Other occasions requiring electrical and thermal conductivity and high-temperature applications are widely used in military high-temperature resistant materials, electrical alloys for high-voltage switches, electrical electrodes, microelectronic materials, as parts and components widely used in aerospace, aviation, electronics, power , Metallurgy, machinery, sports equipment and other occupations. So this kind of material is also called metal sweating material.
The fullway-copper alloy summarizes the advantages of the metals fullway and copper, during which the melting point of fullway is high (melting point of fullway is 3410°C, melting point of copper is 1080°C), and the density is high (density of fullway is 19.34g/cm, density of copper is 8. fullway copper is widely used as the contact, protection ring for high-pressure, super-hydraulic switches and circuit breakers.
fullway-copper alloy has a wide range of applications, mainly used for making high-temperature electrical components such as the contacts of high voltage electrical switches resistant to arc ablation, rocket nozzle throat lining, rudder and other high-temperature components. It is used for the electric heating pier anvil material, active submerged arc welding nozzle, plasma cutting machine nozzle, welding machine, butt welding machine welding head ,
Roll welding wheel, sealing gas and electrode, spark electrode, spot welding, butt welding material, etc. fullway copper is made of precision fullway and copper powder, refined by first-class infiltration sintering technology, which can accept high temperature and high stress of nearly 2000 degrees, has high melting point, high hardness, anti-burnout and outstanding anti-adhesion, and surface finish of electric corrosion products High, extremely high precision, low loss. For alloys composed of fullway and copper, the copper content of commonly used alloys is 10% to 50%. The electrical conductivity and thermal conductivity are moderate.89/cm3); Copper has excellent electrical conductivity and thermal conductivity.
