"A COPPER-BASED METAL ALLOY OF IMPROVED TYPE, PARTICULARLY FOR THE CONSTRUCTION OF ELECTRONIC COMPONENTS" A new copper-based alloy is described, the principal characteristic of which lies in having two different age-hardening temperature intervals corresponding to which significantly different electrical and mechanical characteristics are obtained from an alloy of the same composition; the alloy is composed, in parts by weight, of from 0.05 to 1% Mg, from 0.03 to 0.9% P and from 0.002 to 0.04% Ca, the remainder being Cu with possible very small additions of other alloying elements such as Sn, Zr, Mn and Li. |
