Product Code : ME-W-5N-BR
Unalloyed tungsten bar is produced from pure tungsten powder, the purity is usually quite high, W≥99.95%. Pure tungsten could be worked by forging, drawing, extruding and rolling. Pure tungsten blanks, which are made from tungsten powder by powder metallurgy, are the raw products to process tungsten bars.
Pure tungsten rod/bar is mainly used for: casting ingredients; Machining tool head and a variety of thermal conductivity; Ingredients and additives for steelmaking, ingredients and electrodes for crankshaft and cylinder of advanced automobiles, widely used in the manufacture of rockets, satellites, aircraft and ships. The doped tungsten strips are used to produce the filament or tube filament, which guarantees significant resistance to high temperatures.

A tungsten rod is a cylindrical bar made of tungsten, a rare metal known for its high melting point, high density, and exceptional strength. Tungsten has the highest melting point of all metals, at 3,422 °C (6,192 °F), and the second-highest boiling point, exceeded only by carbon. It also has a high density, approximately twice that of steel, and is one of the hardest metals, making it suitable for a variety of applications.
Tungsten rods are used in a variety of industries, including the aerospace and defense industries, as well as in the manufacturing of electrical contacts, electrodes, and heating elements. They are also used in the production of light bulbs, as the filament in incandescent bulbs, and in the manufacture of electronic devices, such as cathode-ray tubes and vacuum tubes.
Tungsten rods are typically produced by a process called sintering, where tungsten powder is compressed and heated until it bonds together to form a solid rod. The resulting rod is then machined to the desired dimensions and surface finish. Tungsten rods are available in a range of sizes, from a few millimeters in diameter to several centimeters, and can be ordered in various lengths to suit specific applications.
