Aluminum does not rust in the traditional sense like iron does, because it lacks iron, which is essential for rust to form. However, aluminum can undergo a process known as aluminum corrosion, which is quite different from rusting. This difference is crucial because while “aluminum rust” is a misnomer, the corrosion of aluminum still involves a reaction with the environment, albeit through a different mechanism.

Carbon steel magnetic, mainly due to the presence of iron in it. Iron is a magnetic element, and when iron atoms are arranged to form a ferromagnetic region, they form a magnetic moment in that region and exhibit strong magnetism. Carbon steel is an alloy of iron and carbon, which has a high content of iron, and therefore carbon steel is also magnetic.
