Claims
- 1. A multi-phase copper alloy comprising;
- a copper alloy matrix CuQ where Q is an element or combination of elements both soluble in copper and reactive with nitrogen;
- and a second phase precipitate QN intragranularly dispersed within said copper alloy matrix.
- 2. The copper alloy of claim 1 wherein Q is selected from the group consisting of titanium, aluminum, chromium, zirconium, silicon and mixtures thereof.
- 3. The copper alloy of claim 2 wherein the concentration of Q is from about 1 to about 10 weight percent.
- 4. The copper alloy of claim 3 wherein the concentration of Q is from about 3 to about 6 weight percent.
- 5. The copper alloy of claim 3 wherein the average cross sectional dimension of said second phase precipitate is under about 3 microns.
- 6. The copper alloy of claim 5 wherein the average cross sectional dimension of said second phase precipitate is about 1 micron.
- 7. The copper alloy of claim 5 further including X, an element or combination or combination of elements soluble in copper and essentially non-reactive with nitrogen such that said copper alloy matrix is CuXQ and said second phase precipitate is QN.
- 8. The copper alloy of claim 7 wherein X is selected from the group consisting of zinc, nickel, tin, cobalt, iron, manganese and mixtures thereof.
