摘要： An aluminum bearing beta copper alloy that on heating to a first temperature shows a transition from an (alpha+beta)-region, an (alpha+beta+gamma)-region or a (beta+gamma)-region to a beta-region.Its average grain size is less than 200 .mu.m and it contains aluminium bearing precipitates, e.g. Co-Al-precipitates, the average size of which is less than 10 .mu.m and which are insoluble in the alloy below a second temperature that is higher than said first temperature.The fine grain structure guarantees an excellent mechanical and thermomechanical behavior of the alloy, while the aluminium bearing precipitates guarantee that this structure and hence the advantageous behavior of the alloy is maintained as long as the alloy is not heated to said second temperature.
