Abstract

The invention discloses an aluminum alloy material for door and window. The material consists of the following components by weight percentage: 0.15-0.5% of iron, 0.85-1.5% of magnesium, 5-6% of zinc, 0.05-0.15% of chromium, 0.05-0.15% of titanium, 0.1-0.2% of cerium, 0.1-0.2% of yttrium, 0.1-0.2% of silicon, and 0.1-0.2% of manganese, with the balance being aluminum. The chromium, titanium, cerium, yttrium and other elements in the alloy material improve the resistance to corrosion of the alloy. The cerium, yttrium and other elements improve normal and low temperature toughness and breakability of the alloy. The material improves the ability of heating and the soundness of the weld assembly.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to an aluminum alloy material for doors and windows. Background technique [0002] With the development of science and technology, more and more aluminum alloys are used for doors and windows. Aluminum alloys for doors and windows are different from aluminum alloys for other purposes and need to be more excellent. Ordinary aluminum alloys have average corrosion resistance, low-temperature toughness decreases, and are prone to breakage in winter. At the same time, they have poor heating performance and are prone to instability during welding and installation. Contents of the invention [0003] The object of the present invention is to overcome many shortcomings of ordinary aluminum alloys, and provide an aluminum alloy material for doors and windows. [0004] In order to solve the above-mentioned existing technical problems, the technical solution adopted by the present invention is: an ...
