Electrically conductive spring materials.

摘要

An electrically conductive material consisting essentially of 0.15 to 0.35% of Be, 0.3 to 1.5% of A l , either one or both of Ni and Co in a total amount of 1.6 to 3.5%, in terms of weight, and the balance being Cu with inevitable impurities. The alloy may further contain at least one of Si, Sn, Zn, Fe, Mg and Ti in a total amount of 0.05 to 1.0%, in terms of weight ratio. Each of the Si, Sn, Zn, Fe, Mg and Ti is in an amount of 0.05 to 0.35%.
