Claims
- 1. A spray case copper base alloy having improved properties comprising:
- one or more dispersoid producing first components in an amount of 80-200% of the solid solubility point concentration of the first components in copper;
- one ore more solid state precipitates producing second components in an amount less than the solid solubility concentration limit of the second component copper;
- and the balance copper;
- said alloy having as a structure:
- a copper based matrix;
- a second phase of dispersions of the first component uniformly dispersed throughout said matrix, said dispersoids having a mean particle size of from about 0.1 micron to about 0.5 micron, said dispersoids being selected from the group consisting of iron, cobalt, niobium, vanadium, and mixtures thereof; and
- a third phase of a solid state precipitate of the second component.
- 2. The spray cast alloy of claim 1 wherein said solid state precipitates are selected from the group consisting of beryllium, chromium, a combination of nickel and silicon, a combination of nickel and aluminum, magnesium, a combination of magnesium and phosphorus, and a combination of nickel and tin, and mixtures thereof.
