COPPER ALLOY FOR ELECTRONIC AND ELECTRICAL PARTS, PLANAR ROW MATERIAL AND ROW MATERIAL HAVING DEFORMED CROSS SECTION, AND LEAD FRAME FORMED BY THE PLANAR ROW MATERIAL OR ROW MATERIAL HAVING DEFORMED CROSS SECTION
COPPER ALLOY FOR ELECTRONIC AND ELECTRICAL PARTS, PLANAR ROW MATERIAL AND ROW MATERIAL HAVING DEFORMED CROSS SECTION, AND LEAD FRAME FORMED BY THE PLANAR ROW MATERIAL OR ROW MATERIAL HAVING DEFORMED CROSS SECTION
PROBLEM TO BE SOLVED: To provide an inexpensive copper alloy for electronic and electrical parts having high electric conductivity, excellent in heat resistance and capable of preventing the reduction of productivity and yield in a transistor assembling stage by using a lead frame to be produced, to provide a planar row material and a row material having a deformed cross section, and to provide a lead frame produced by using the same. ;SOLUTION: This copper alloy for electronic and electrical parts has a composition containing one or more selected from Fe, Ni and Co in 0.004 to 0.07 mass % in total and 0.005 to 0.05 mass % P, and the balance Cu with inevitable impurities.;COPYRIGHT: (C)2001,JPO
