Abstract
The invention discloses high-strength corrosion resistance aluminum alloy for a door and window, and relates to the field of construction materials. The high-strength corrosion resistance aluminum alloy comprises the components including, by weight, 0.4-0.6% of Si, 0.5-1% of Fe, 1.6-5% of Cu, 0.2-0.4% of Mn, 1.5-4% of Mg, 2-3% of Zn, 0.18-0.25% of Ti, 0.5-0.8% of Cr, 0.3-0.45% of Ni, 0.1-0.5% of Mo, 0.02-0.08% of V, not larger than 0.15% of total impurities and the balance Al. The high-strength corrosion resistance aluminum alloy solves the problem that existing aluminum alloy for the door and window is low in strength and corrosion resistance.
Description
Technical field
The present invention relates to architecture engineering material technical field, especially a kind of high-strength corrosion-resisting door and window aluminium alloy.
Background technology
Aluminum alloy doors and windows aluminium alloy extrusions are made into frame, stile, fan material component, assemble together with handware with glass, sealing member again, it has good anti-wind pressure, stopping property, heat retaining property and answering property of diaphragm relative to traditional door and window, is extensively promoted the use of in construction work.Existing high-strength corrosion-resisting door and window aluminium alloy just there will be difficult push-and-pull or folding in use for some time, larger noise can be produced in push-and-pull or moving process, the problems such as larger gap are produced between sash and guide rail, this is because the intensity of aluminium alloy extrusions is lower, in use be subject to the impact of the shock produced in blast and push-and-pull or moving process, cause distortion to cause.Simultaneously, door and window in use can experience the impact exposing to the weather or be subject to temperature and humidity change, main raw because of the aluminium alloy extrusions of aluminum alloy doors and windows is aluminium, it is very easily oxidized in atmosphere, and be corroded, cause the variable color of door and window aluminium alloy extrusions, distortion, shorten the work-ing life of aluminium alloy extrusions, therefore, usually surface treatment can be carried out to aluminium alloy extrusions, existing technique for surface treatment of aluminium alloy sections has anodic oxidation, electrolytic coloring, electrophoretic painting, powder spraying, F-C paint sprays, wire drawing etc., these process of surface treatment all play certain anticorrosion effect, but still difficulty meets the requirement of existing building material to work-ing life, and after long-term use, aluminum alloy base material is exposed in aluminium alloy section surface wearing and tearing, the oxidation-resistance of aluminum alloy base material itself can meet the service requirements of material of construction.
Summary of the invention
The object of this invention is to provide a kind of high-strength corrosion-resisting door and window aluminium alloy, it can solve existing door and window aluminium alloy and there is intensity and the low problem of erosion resistance.
In order to solve the problem, the technical solution used in the present invention is: a kind of high-strength corrosion-resisting door and window aluminium alloy is made up of the component of following weight percentage: Si0.4-0.6%, Fe 0.5-1%, Cu1.6-5%, Mn0.2-0.4%, Mg1.5-4%, Zn2-3%, Ti0.18-0.25%, Cr0.5-0.8%, Ni0.3-0.45%, Mo0.1-0.5%, V0.02-0.08%, add up to Za Zhi≤0.15%, all the other are Al.
In the technical scheme of above-mentioned high-strength corrosion-resisting door and window aluminium alloy, technical scheme can also be more specifically: Si0.48%, Fe0.5%, Cu3.8%, Mn0.3%, Mg2.5%, Zn2.5%, Ti0.2%, Cr0.68%, Ni0.38%, Mo0.32%, V0.06%.
