Tungsten Nickel Copper Bar Picture:
High Temperature Tooling
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.
