Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to an aluminum alloy. Background technique [0002] Aluminum alloy is an alloy composed of aluminum as a matrix element and then adding one or more alloying elements.

Problems solved by technology

The density of aluminum alloy is low, but its strength is relatively high, and it has excellent electrical conductivity, thermal conductivity, and corrosion resistance. At present, household doors, windows and windows are mostly made of aluminum alloy materials, but in daily life, aluminum alloy materials are relatively rigid. , the elasticity is insufficient, so if it encounters impact in life, it will break, and the aluminum alloy material will pop out, which may cause personnel scratches

[0003] In the process of installing aluminum alloy window frames for home decoration in the early stage, the window frame was broken due to the worker's operation error, and the debris flew out and scratched a worker. In response to this, the idea of ​​​​improving the aluminum alloy material for doors and windows sprouted; and consulted a large number material,

[0004] Among them, a material about aluminum alloy materials for doors and windows was found, and the purpose of improvement was determined, such as a Chinese patent with a patent number of 2013102233834, which discloses an aluminum alloy material for doors and windows, which is composed of the following weight percentages Composition of each component: iron 0.15%-0.5%, magnesium 0.85%-1.5%, zinc 5%-6%, chromium 0.05%-0.15%, titanium 0.05%-0.15%, cerium 0.1%-0.2%, yttrium 0.1% ~0.2%, silicon 0.1%~0.2%, manganese 0.1%~0.2%, and the balance is aluminum; the corrosion resistance of the alloy is improved through chromium, titanium, cerium, yttrium and other elements in the alloy material, and the corrosion resistance of the alloy is improved through cerium, yttrium, etc. Elements improve the normal and low temperature toughness and fracture of the alloy, improve the heating workability and the firmness of the weldment; but although the low temperature toughness is improved, the elasticity of the aluminum alloy material is still unable to be improved, and the strength is too large, which loses the impact resistance. Flexible, and broken fragments can easily fly out, posing a hazard

[0005] Therefore, I conduct research on this issue to solve the problems of insufficient flexibility of current door and window aluminum alloy materials, poor impact resistance, and easy to fly out due to impact fracture; accordingly, the present invention proposes an aluminum alloy
