Production process of tungsten rods

Materials—CIP --- IF induction sintering --- forging --- annealing—mechanical processing --- tungsten rods

Production equipments

Coolisostatic pressing machine(CIP), IF induction sintering furnace, forging machine, coreless grinder ,CNC vertical turning machine, wire cutting machine.

Applications of tungsten rods

Since the heavy is18.3 g/cm3,and the melting point has reached 3380^oC, tungsten rod with high temperature resistance and high creep resistance often used in high-temperature furnace, vacuum furnace, and sapphire crystal furnace.

Bango Alloy can provide tungsten bars and rods that made with tungsten powder which purity is 99.95%. After sintering and forging, the density of tungsten rod basically comes close to tungsten’s theory density, so they have a good high-temperature strength and electrochemical corrosion resistance.
