| Production process of tungstun 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. |
| Application of tungstun rods | Since the heavy is18.3 g/cm3,and the melting point has reached 3380oC, 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.
