BERYLLIUM-NICKEL-COPPER LEAN ALLOY HAVING HIGH ELECTRIC CONDUCTIVITY AND STRESS RELAXATION RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a beryllium-nickel-copper lean alloy having high electric conductivity and stress relaxation resistance. ;SOLUTION: This alloy has a composition represented by a composition formula which consists of 0.15-0.5& Be, 0.40-1.25& Ni, 0-0.25& Sn, 0.06-1% Zr and/or 0.06-1% Ti, and the balance copper and in which the total content of Zr and Ti is regulated to about 0.06-1%0 In this alloy, electric conductivity, bendability, and stress relaxation resistance are improved without deteriorating strength.;COPYRIGHT: (C)1998,JPO
