Pure Tungsten
Tungsten, also referred to as Wolfram, is a chemical element with the chemical symbol W and atomic number 74. After Carbon, Tungsten has the highest melting point of all elements. Tungsten is among the heaviest metals found on Earth. It has excellent high temperature mechanical properties, with the lowest expansion coefficient and highest conductivity of all metals.
We provide tungsten rolling products (plate, sheet, disc, foil), tungsten drawing and forging products (tungsten block, rod, bar, wire), tungsten machined parts (tungsten crucible, tungsten heater, tungsten furnace system, tailor-made tugnsten), tungsten wire mesh. Except the shaped and machined tungsten products, our specialty tungsten product is tungsten granules (broken by forged tungsten), porous tungsten (low temperature sintered tungsten). Please send us your request to sales@edge-techind.com.
