The paper describes the mechanical and corrosion properties of three heat treatable extruded Al-Mg-Si aluminum alloys. The alloys were tested as T5 tempered (air-quenched directly on the press and artificially aged) after processing by the extrusion of semi-continuous cast and homogenized billets. The addition of small amounts of zirconium and manganese in the base AIMgSiO.7 alloy increased the strength, reaching 310 MPa of tensile strength and increased the corrosion rate by 15% in aqueous sodium chloride solution.
