Tungsten metal has the 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.
Tungsten sheet application
After rolling and processing with deflection reaching 60% , the density of tungsten sheet basically comes close to tungsten’s theory density. Therefore, tungsten sheet possesses the properties of high shield, heating tape, connecting pieces applied in vacuum furnace, titanium sputtering target applied in plasma coating film, and high temperature resistance boats.
