ABSTRACT:
Spray cast copper-manganese-zirconium alloys are disclosed. In one embodiment, the alloy is spray cast in nitrogen and contains from about 1 ppm to about 20 ppm of dissolved nitrogen. In a second embodiment, the alloy contains an addition selected from the group consisting of chromium, titanium, erbium and mixtures thereof. The alloys are useful for sound damping as the combination of zirconium and the addition inhibits degradation of the specific damping capacity of the alloy.
