铝窗花首先是材质的可塑性与优势。由于材质是以铝为主，硬度比较小，所以可塑性非常好，常见一些带压花、雕花铝镁合金立柱就是例子。虽然铝材硬度比较小，但是加上镁元素，成为合金材质，硬度就大大提升了。而且重量非常轻，易于装拆。

最后是氧化性。铝材质是不会生锈的，但是会氧化。长时间与空气中的湿气接触，表面会氧化，然后形成一层薄膜叫氧化铝，起到一个保护内部不受腐蚀的作用。

The first is the plasticity and superiority of the material. Since the material is mainly aluminum, the hardness is relatively small, so the plasticity is very good, common some with embossing, carved aluminum magnesium alloy column is an example. Although aluminum hardness is relatively small, but add magnesium element, become alloy material, hardness increases greatly. And the weight is very light, easy to install.And then finally oxidation. Aluminum will not rust, but it will oxidize. Contact with moisture in the air for a long period of time oxidizes the surface and forms a thin film called alumina, which ACTS as a protection against corrosion.
