Copper alloys for thermal spray
The Osprey range of copper thermal spray alloys includes:
- Self-bonding alloys
- Flame spraying and metallizing alloys
Self-bonding copper alloys
Self-bonding copper alloy with optimum characteristics for applications where a single metallized coating is preferred. With adequate surface preparation and suitable thermal spraying equipment, high-density coatings are produced with high bond strengths. For corrosive environments, the deposit will require a sealant. ≥

Flame spraying and metalizing copper alloys
Gas atomized metal powder suitable for flame spraying or metalizing, without subsequent fusion of the coating. Good surface preparation is fundamental to the success of this process and the application of a bond coat (SB 80) is recommended.
Alloy | Description | Cu | Al | Fe | Ni |
---|---|---|---|---|---|

Cold spray copper alloys
High-purity copper powder with low oxygen content where high thermal and electrical conductivity in the coating is required.
