Abstract
Copper alloys, methods for producing copper alloys, and copper tubes are provided. The copper alloys include an alpha solid solution formed from phosphorous deoxidized copper and at least one trace element comprising tin. The content of tin ranges from about 0.1% to about 2.0% by weight of the copper alloy. The trace element can further include zinc in an amount from about 0.05% to about 1.0% by weight of the copper alloy. The copper alloys have an increased tensile strength due to the strengthening effect by the alpha solid solution formed by phosphorous deoxidized copper and tin as the trace element, and accordingly a copper tube made from the copper alloy has a significantly improved pressure resistance.
