The invention discloses a novel high-strength
corrosion-resistant aluminum
alloy door and window. The novel high-strength
corrosion-resistant aluminum
alloy door and window comprises an aluminum
alloy frame. The aluminum alloy frame comprises, by weight, 0.2% of Mg, 2.0% of Si, 4.0% of Cu, 0.2% of Mn, 0.2% of Fe, 0.1% of Zr, 0.1% of Er, 0.01% of Cr, 0.01% of Ni, 0.1% of Ti, and the balance Al. A finished product is obtained after the aluminum alloy frame is subjected to (1)
smelting, (2) adding of three
metal refinement modifiers of Al-5Ti-B, Al-10Sr and RE, (3) two hours of standing under the condition of 100 MPa, and forming of a cast
ingot, (4) five passes of hot rolling, and three passes of cold rolling under
ultrasonic vibration, (5) modification with C
laser and V
laser, and (6) surface treatment with a
octadecyltrichlorosilane solution. According to the novel high-strength
corrosion-resistant aluminum alloy door and window, various methods are used for conducting modification and treatment on materials of the aluminum alloy frame, the completeness of an oxidation film can still be kept when the aluminum alloy frame is subjected to corrosion under adverse working conditions, so that
metal failure is avoided, and the requirements of current industrial development are met.
