ABSTRACT OF THE DISCLOSURE Copper alloys having high conductivity at room temperature and superior resistance to softening at elevated temperatures comprise oxygen-free copper con- taining small but effective amounts of selenium and manganese, and in particular about 4 to about 100 parts per million selenium and about 4 to about 100 parts per million manganese. The alloys can advantageously be used in place of copper-silver alloys, with a realization of improved properties and reduced cost.
