Abstract
Disclosed herein are nickel beryllium alloys having improved corrosion and hardness characteristics relative to known nickel beryllium alloys. The alloys have a chemical composition with about 1.5% to 5% beryllium (Be) by weight, about 0.5% to 7% niobium (Nb) by weight; and nickel (Ni). Up to about 5 wt % chromium (Cr) may also be included. The alloys display improved hardness and corrosion resistance properties.
