Provide W-1 99.95% Tungsten Products Wolfram Plates for Vacuum Furnace / Sapphire Growth Tungsten metal has high melting point, good thermal and electrical conductivity as well as low vapor pressure at high temperatures. Such properties make tungsten metal a candidate for use as a high performance material in a variety of high temperature products and processes. In spite of its characteristic of oxidizing easily when heated in air, tungsten metal is widely utilized as a heating element material in industrial furnaces.
