摘要:
A copper alloy having high strength, high electrical conductivity, and excellent bendability, the copper alloy containing, in terms of mass %, 0.4 to 4.0% of Ni; 0.05 to 1.0% of Si; and, as an element M, one member selected from 0.005 to 0.5% of P, 0.005 to 1.0% of Cr, and 0.005 to 1.0% of Ti, with the remainder being copper and inevitable impurities, in which an atom number ratio M/Si of elements M and Si contained in a precipitate having a size of 50 to 200 nm in a microstructure of the copper alloy is from 0.01 to 10 on average, the atom number ratio being measured by a field emission transmission electron microscope with a magnification of 30,000 and an energy dispersive analyzer. According to the invention, it is possible to provide a copper alloy having high strength, high electrical conductivity, and excellent bendability.
