The heating process is also a dehydrogenizing process to the tungsten alloy. Tungsten copper alloy is made of fine tungsten and copper powders, refined by first-class immersion sintering process, can withstand high temperature and high stress of nearly 2000 degrees, has high melting point, high hardness, anti-burning and good anti-adhesion, and electro-erodes the product surface High finish, high precision, low loss. Other materials for this applications are copper-molybdenum alloy, AlSiC, and Dymalloy. Melting point of Tungsten is 3410C. Tungsten copper alloy is consisting of tungsten and copper, copper content of 10% to 50%. [6] Copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding. 10.52. More about tungsten heavy alloy properties>>>. The alloy is prepared by powder metallurgy, which has good electrical and thermal conductivity, good high-temperature strength, and certain plasticity. Free P&P. 1pc 52mm Pure Tungsten Element Rod Electrodes Tesla Coil 99.95%. Copper Tungsten Alloys are Tungsten based composite materials that are a strong refractory metal material manufactured by a stringently controlled process involving pressing, sintering and infiltrating with Copper or Silver. Cyprus, a Mediterranean island, was known as an ancient source of mined copper. We stock a range of alloys from 90% to 97% pure tungsten in a matrix of nickel/copper or nickel/iron. CHEMETAL USA established with the goal of providing the easiest and most efficient services to our North American customers. Tungsten is a rare high-melting-point metal that can increase the high-temperature hardness of steel. T ungsten copper alloy is a pseudo alloy composed of tungsten and copper. Sponsored.
