Precipitation Hardening Copper Alloys
Besides the naturally hard copper materials precipitation hardening copper alloys play also an important role as carrier materials for electrical contacts. By means of a suitable heat treatment finely dispersed precipitations of a second phase can be achieved which increase the mechanical strength of these copper alloys significantly. Copper-Beryllium Alloys (Beryllium Bronze)The cause for precipitation hardening of CuBe mat...
