<p><P>PROBLEM TO BE SOLVED: To provide a copper alloy having both of such high electroconductivity and heat resistance as to be capable of being used for a heat radiation plate in a power module in which a high current is passed and for which a demand will increase in the future and of being used for a power distribution member for automobiles that will be electrified. <P>SOLUTION: The heat-resistant copper alloy with high electroconductivity is a tin-containing copper alloy with adequate heat resistance, and has such a composition containing an iron component as to include, by mass%, 0.04-0.08% Sn, 0.003-0.010% P, 0.001-0.010% Fe and the balance copper with unavoidable impurities. The method for producing the heat-resistant copper alloy with high electroconductivity does not need to use an oxygen-free atmosphere in a melting and casting step, and thereby can make the production cost inexpensive. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
