Tungsten powders

Tungsten is a steel-grey element with bright metallic lustre and a melting point of ~3400oC, the highest of all metals. Its density is also one of the highest at 19.3 g/cc. Depending upon its worked condition, Tungsten has a hardness range of ~350-450 HV.

Other important properties and characteristics making Tungsten a valuable material for metallurgical designers:

• High temperature strength and creep resistance.
• High electrical resistivity.
• Good thermal conductivity.
• Low vapour pressure.
• Low thermal expansion.
• Vibration damping.
• Radiation shielding.

Applications

Some of Tungsten's main uses are in:

• Tungsten carbide for cutting, drilling, sawing and grinding tools.
• Balancing weights for rotating blades, wheels, flywheels, discs, shafts, gyroscopes, pendulums, governors, floats, actuators, stabilisers.
• Sporting weights for darts, fishing, diving, exercise, golf clubs, tennis racquets, saddles.
• Anti-vibration tooling.
• Bullets, penetrators, pellets, shot, charges.
• Armour plate.
• Lamp filaments.
• Heating elements, reflectors, shields, dissipaters.
• Electrical contacts, connections and electrodes.
• Anodes and cathodes.
• Ionising radiation shields.
• Sputtering discs.
• Furnace furniture.
• Welding electrodes and guides.
• Evaporation boats and reaction boats.
• Hot extrusion and die-casting tools.
• Flame nozzles and ignition tubes.
• Superalloys and special steels.
• Spark erosion electrodes.
• Diamond and CBN tools.
