What I claim is :
1. A process for improving the physico-mechanical properties of alloys of beryllium with nickel consisting in introducing into nickel-beryllium alloys containing beryllium in the proportion of about 1.4 to 1.7%, as a metallic substance acting as a diffusing, solubilizing and homogenizing agent for beryllium, molybdenum in a proportion from 0.3 up to 1%, the balance being substantially all nickel, heating the alloys so constituted at a temperature of about 1000 to 1020° C., for 30 to 45 minutes, then cooling the same rapidly and subjecting them to an annealing treatment producing the reprecipitation of the hardening constituent diffused in the alloys.

3. A nickel-beryllium alloy containing beryllium in the proportion of about 1.4 to 1.7% and as a metallic substance acting as a diffusing, solubilizing and homogenizing agent for beryllium, molybdenum in a proportion from 0.3 up to 1%, the balance being substantially all nickel.
