- Density:16.8-18.8g/cm3
- Rods Size:dia(1.5 -200) x Length<500mm
Plate size: 0.1min Thickness*W*L
Production Method
1), Blending of tungsten powder with other metal powders and a bonding agent, cooling and sieving.
2), Pressing the blended powder to the required shape (allowing for shrinkage during the final processing), and shaping the green part component.
3). Pre-sintering the pressed components to remove the bonding agent.
Final sintering in the hydrogen fed furnace to fuse the powder particles together.
4). Supplied in bar, square, round and rectangle sizes are available in rough oversize, or turned or ground to exact requirements. Components can also be produced to customer drawings.
