Abstract
Official abstract text for this publication.
A copper alloy having the following composition (in % by weight): from 10.6 to 18% of Al, from 10.5 to 14.5% of Ni, optionally up to 2% of Fe, optionally up to 1% of Co, optionally up to 0.5% of Ti, optionally up to 0.5% of Mn, optionally up to 0.15% of B, optionally up to 0.1% of Ca, and optionally up to 0.1% of C, with the balance being copper and unavoidable impurities. Nickel aluminides of the NiAl type are embedded as precipitates in the microstructure of the alloy.
First claim
Opening claim text (preview).
The invention claimed is: 1. A copper alloy consisting of the following composition in % by weight: from 10.6 to 18% of Al, from 10.5 to 14.5% of Ni, optionally up to 2% of Fe, optionally up to 1% of Co, optionally up to 0.5% of Ti, optionally up to 0.5% of Mn, optionally up to 0.15% of B, optionally up to 0.1% of Ca, and optionally up to 0.1% of C, with the balance being copper, characterized in that nickel aluminides of the NiAl type are embedded as precipitates in the microstructure of the alloy. 2. The copper alloy according to claim 1 , characterized in that the proportion of aluminum is at least 12% by weight and not more than 16% by weight. 3. The copper alloy according to claim 1 , characterized in that the proportion of nickel is at least 11% by weight and not more than 13% by weight. 4. The copper alloy according to claim 1 , characterized in that the ratio of the proportion of aluminum in % by weight to proportion of nickel in % by weight is at least 0.95 and not more than 1.28. 5. A sliding element comprising a copper alloy according to claim 1 . 6. A plug connector comprising a copper alloy according to claim 1 . 7. A sealing element comprising a copper alloy according to claim 1 . 8. A tool comprising a copper alloy according to claim 1 . 9. A spring element comprising a copper alloy according to claim 1 . 10. A filter element comprising a copper alloy according to claim 1 .
