<p>A low cost electroconductive spring material for use in electrical devices having excellent electroconductivity and spring performance consists of from 1.8 to 3.0% by weight of Ni, from 0.15 to 0.35% by weight of εe, from 0.2 to 1.2% by weight of Si and the balance Cu. This low cost electroconductive spring material can be applied as electric devices. The material may further contain from 0.05 to 3.0% by weight in total of at least one component selected from Sn, Al and Zn provided that each such component is in the range of 0.05 to 1.5% by weight, or may contain from 0.01 to 2.0% by weight in total of at least one component selected from Co, Fe, Zr, Ti and Mg provided that each such component is in the range of .0.01 to 1.0% by weight.</p> |
