Beschreibung
Zusammenfassung:	An aluminum alloy connector which is excellent in extrusion property and sacrificial anode property, the connector being extruded in a hollow shape from an aluminum alloy extrusion material consisting of 0.2 to 0.8% (hereinafter, "%" means "mass %") of Si, 0.45 to 0.9% of Mg, 1.0 to 3.5% of Zn, 0.001 to 0.2% of Ti and the balance of Al plus unavoidable impurities. An electric potential of said aluminum alloy extrusion connector is lower than an electric potential of a pipe member made of an Al-Mg-Si series alloy or an Al-Mn series alloy which is to be swaged to the connector, by 100 mV or more.
