摘要： The invention relates to a copper alloy which is used for mechanically stressed components which, during operation, are subjected to vibrations and/or impacts to produce the same, and have particularly good mechanical damping properties. The composition of said copper alloy depends upon the utilisation temperature or working temperature of the component. Said copper alloy consists of 2-12 wt.-% manganese, 5-14 wt.-% aluminum and individually or in total 0-18 wt.-% of one or several elements, nickel, iron, cobalt, zinc, silicon, vanadium, niobium, molybdenum, chromium, tungsten, beryllium, lithium, yttrium, cerium, scandium, calcium, titanium, phosphorous, zirconium, boron, nitrogen, carbon, whereby each element does not contain more that 6% and 100 wt.-% copper. The alloy is obtained by adapting the martensite-austenitic conversation temperatures or the associated intervals MS-MF and/or AS-AF to a predetermined utilisation temperature or working temperature of the component by varying the weight proportion of the above-mentioned alloy component during melting thereof. The damping can reach above 70%.
