How Tungsten Carbide Is Made
From raw tungsten powder to finished cemented carbide — our controlled powder-metallurgy process in five stages.
- Step 1
Carburization
When tungsten and carbon are heated in a furnace, they combine to form tungsten carbide (WC) — the hard base material.
- Step 2
Mixing & Granulation
Cobalt and other binder metals are blended with the tungsten carbide, then dried and granulated into a fine, uniform powder.
- Step 3
Pressing
The powder is compacted in a mould into the required shape. At this stage the part is still soft — about as hard as chalk.
- Step 4
Sintering
The pressed part is sintered at about 1400°C (2550°F) in a vacuum or non-oxidizing atmosphere, fusing it into dense cemented carbide.
- Step 5
Grinding & Finishing
Finally, the hardened carbide is precision-ground, shaped, and finished to exact tolerances and surface specifications.
