Abstract
A copper alloy disclosed in the present description has a basic alloy composition represented by Cu100-(x+y)SnxMny (where 8≤x≤16 and 2≤y≤10 are satisfied), in which a main phase is a βCuSn phase with Mn dissolved therein, and the βCuSn phase undergoes martensitic transformation when heat-treated or worked.
