A copper alloy having an improved combination of yield strength and electrical conductivity consists essentially of, by weight, from 1% to 2.5% of nickel, from 0.5% to 2.0% of cobalt, from 0.5% to 1.5% of silicon, and the balance is copper and inevitable impurities. Further, the total nickel plus cobalt...http://www.google.es/patents/US7182823?utm_source=gb-gplus-sharePatente US7182823 - Copper alloy containing cobalt, nickel and silicon
