The invention discloses a corrosion-resistant aluminum alloy profile and an extrusion method thereof. The corrosion-resistant aluminum alloy profile is composed of, by mass, 0.4%-0.6% of Mg, 0.6%-0.9% of Si, 0.1%-0.3% of SN, 0.1%-0.3% of Ta, 0.1%-0.3% of Ge, not larger than 0.15% of Fe and the balance Al, wherein 0.4%<=(Sn+Ta+Ge)<=0.6%. According to the corrosion-resistant aluminum alloy profile, the specific alloy composition constituting and the extrusion method of the corrosion-resistant aluminum alloy profile are designed, recrystallization and grain growth are restrained, the aluminum alloy profile obtains single fiber grain structures in the extruding direction, the strength, breaking tenacity and stress corrosion resistance property of the aluminum alloy profile are improved, the beneficial effect of high combination property is achieved, the corrosion-resistant aluminum alloy profile can be widely applied to buildings, electric products, mechanized equipment, transportation, aerospace and other fields, and the wide application prospect is achieved.
