Abstract
The invention discloses aluminum alloy for impact-resistant doors and windows and relates to the field of constructional engineering materials. The aluminum alloy comprises, by weight, 0.28-0.35% of Si, 0.1-0.2% of Fe, less than 0.2% of Cu, 0.62-0.88% of Mn, 0.8-1.3% of Mg, less than 0.1% of Zn and lt, 0.05-0.15% of Ti, 0.03-0.08% of Cr, 0.03-0.06% of Sc, 3.6-5.8% of Gd, not more than 0.15% of total impurities and the balance Al. The aluminum alloy has the advantage that the problems that existing aluminum sections for the doors and windows are poor in strength and irresistible to impact are solved.
Description
Technical field
The present invention relates to architecture engineering material technical field, especially a kind of shock-resistant 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 door and window aluminium alloy extrusions 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, impact resistance are 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.
Summary of the invention
The object of this invention is to provide a kind of shock-resistant door and window aluminium alloy, it can solve existing door and window aluminium alloy extrusions and there is low, the not impact-resistant problem of intensity.
In order to solve the problem, the technical solution used in the present invention is: a kind of shock-resistant door and window aluminium alloy is made up of the component of following weight percentage: Si0.28-0.35%, Fe 0.1-0.2%, Cu ﹤ 0.2%, Mn0.62-0.88%, Mg0.8-1.3%, Zn<0.1%, Ti0.05-0.15%, Cr0.03-0.08%, Sc0.03-0.06%, Gd3.6-5.8%, add up to Za Zhi≤0.15%, all the other are Al.
In the technical scheme of above-mentioned shock-resistant door and window aluminium alloy, technical scheme can also be more specifically: Si0.32%, Fe 0.12%, Cu0.1%, Mn0.78%, Mg1.1%, Zn0.06%, Ti0.1%, Cr0.05%, Sc0.04%, Gd4.3%.
Further, Si0.28%, Fe 0.1%, Cu0.15%, Mn0.62%, Mg0.8%, Zn0.05%, Ti0.05%, Cr0.03%, Sc0.03%, Gd3.6%.
Further, Si0.35%, Fe 0.2%, Cu0.1%, Mn0.88%, Mg1.3%, Zn0.04%, Ti0.15%, Cr0.08%, Sc0.06%, Gd5.8%%.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: add Sc, Gd, improve aluminum alloy organization, improve the intensity of alloy, Kang La Qiang Du≤250MPa, Qu takes Qiang Du≤210MPa, and Yan Shen Shuais≤and 10%, the impact resistance of aluminium alloy extrusions strengthens, and prevents the generation of distortion.
