Cobalt-based Alloy Powder (Co-Cr-W) Description
Cobalt-based alloy powder is produced by melting suitable amount of tungsten and carbon or molybdenum into the cobalt-chrome alloy for strengthening. As carbon has low solubility in cobalt, there will generate WC, W2C, W6C and other carbides, which keep the alloy maintain excellent intension and rigidity under high temperature (800°С).

Cobalt-based Alloy Powder Properties
• High Strength: Cobalt-based alloys exhibit excellent strength, maintaining mechanical properties at high temperatures.
• Wear Resistance: These alloys are highly resistant to wear and abrasion, making them ideal for cutting tools and wear parts.
• Corrosion Resistance: Outstanding resistance to corrosion and oxidation, suitable for harsh environments and chemical applications.
• Hardness: High hardness, which provides durability and extends the lifespan of components.
• Toughness: Good toughness, allowing for impact resistance and reducing the risk of fracture under stress.
• Heat Resistance: Superior performance at elevated temperatures, making them suitable for high-temperature applications.
• Biocompatibility: Certain cobalt-based alloys are biocompatible, making them suitable for medical implants.
Cobalt-based Alloy Powder (Co-Cr-W) Application
With excellent resistance of high temperature, oxidation and thermal fatigue, Cobalt-based Alloy Powder (Co-Cr-W) can be applied to a various process, such as:
• oxyacetylene spraying or overlaying
• HVOF/HAFA spraying
• plasma transferred arc (PTA) overlaying
• plasma spraying
• laser overlaying
• induction melting overlaying
Cobalt-based Alloy Powder (Co-Cr-W) Packing
25KG per drum or as required
Our Cobalt-based Alloy Powder (Co-Cr-W) is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
