Our tungsten round bar is made from 99.90% pure tungsten powder shaped into rounds and rectangles.
Tungsten rods have a minimum density of 17.5g/cm3. Under typical atmospheric conditions, a tungsten bar maintains high stability and doesn't react with water, air, or sulfuric acid (HCl). A mild reaction with acid begins when heated to about 80 and 100 °C. The bar easily oxidizes in an oxygen environment.

The 99.999 percent pure tungsten rod are used as parts for high-standard bearing steels, automobiles, high-speed trains, extremely precise equipment, and cutting-edge weapons. The raw materials for ingredients are typically cast, unique steel is forged, and steel wires are typically drawn using 99.95 percent pure tungsten bars. Furthermore, it is widely employed in furnaces for sapphire crystals, vacuums, and high temperatures. Tungsten bar is also used to build ships, satellite airplanes, artillery rockets, and guns.
