Cobalt-based alloy powder (Co-Cr-W) Description
Cobalt-based alloy powder is produced by melting a specified amount of tungsten and carbon or molybdenum into the cobalt–chromium matrix to increase reinforcement. Given that carbon exhibits limited solubility in cobalt, WC, W2C, W6C and other carbides form, thereby imparting the alloy with high strength and stiffness at temperatures of 800°C.

- Plasma spraying
- Laser cladding
- Inductive melting
Cobalt-based alloy powder (Co-Cr-W) Packaging
25 KG per drum or as required
Our cobalt-based alloy powder (Co-Cr-W) is clearly labelled to ensure accurate identification and quality control. Measures are taken to prevent damage during storage or transport.
