ABSTRACT:
A higher order beryllium-nickel-copper alloy a process for making the same, and an article of manufacture comprising the alloy, the alloy being represented by the formula (0.15-0.5% Be) +(0.40-1.25% Ni)+(0-0.25% Sn)+[(0.06-1% Zr) and/or (0.06-1% Ti)], the balance copper, where the sum of % Zr and % Ti is generally within a range of 0.06% and 1%, the alloy being characterized by improved electrical conductivity, bend formability and stress relaxation resistance without sacrificing strength.
