Aluminum alloys contain almost no iron, and without iron, the metal will not rust, but it will oxidize. When the alloy is exposed to water, aluminum oxide film forms quickly on the surface. The hard oxide layer is resistant to further corrosion and protects the underlying metal.
Even with the possibility of corrosion, steel is harder than aluminum. Most spinnable tempers and alloys of an aluminum dent, ding or scratch more easily as compared to steel. Steel is strong and less likely to warp, deform or bend underweight, force or heat.
It has an excellent strength-to weight ratio, and it is ideally used for highly stressed parts.
Can Aluminium Rust? Aluminium doesn't rust. But, it's essential also to note that aluminium in its pure form, is a highly reactive metal. Technically, pure aluminium dissolves when exposed to water but, it's reactive nature could also be its greatest asset.
Tin foil is stiffer than aluminium foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminium and other materials for wrapping food.
Aluminum has 1000 series, 2000 series, 3000 series, 4000 series, 5000 series, 6000 series, 7000 series and 8000 series. Different alloys have different applications.
