COPPER ALLOY WITH HIGH STRENGTH AND HIGH ELECTRICAL CONDUCTIVITY

摘要

Disclosed is a copper alloy with high strength and high electrical conductivity, which contains more than 1.0% by mass but less than 4% by mass of Mg and more than 0.1% by mass but less than 5% by mass of Sn with the balance made up of Cu and unavoidable impurities. The copper alloy with high strength and high electrical conductivity has a mass ratio of the Mg content to the Sn content, namely Mg/Sn of not less than 0.4. The copper alloy with high strength and high electrical conductivity may additionally contain more than 0.1% by mass but less than 7% by mass of Ni.
