The alloys according to the present invention afford a considerable technical progress in the manufacture of springs, needles and ali other objects or articles which especially necessitate a maximum of elasticity even under very high mechanical stresses with a great hardness and also a greatly reduced oxidisability and a considerable facility for manufacture without any appreciable oxidation.
Alloys are especially obtained which possess a very high mechanical strength either as castings or as machined pieces. These alloys possess a very great hardness and a very low consumption through wear and can thus be used, among other things for ball or roller bearings, supports, springs as, for instance, laminated springs, and the like.
The alloys according to the present invention, for instance the Ni-Be-Mo, possess extremely high mechanical and electrical properties and take a good temper after heating at a temperature considerably lower than that required for the usual beryllium alloys, which has the advantage of lessening and practically removing the risk of approaching the fusion or disintegration temperature of the alloy. The solubilizing and homogenizing metal has the effect in this respect of lowering the temperature which is necessary for the intersolubilisation of the constituents of the alloy.
