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, that increases the mechanical strength of these copper alloys significantly.
Copper-Beryllium Alloys (Beryllium Bronze)
The cause for precipitation hardening of CuBe materials, is the rapidly diminishing solubility of beryllium in copper as temperature...
