Stainless Steel vs. Aluminum: Which is Better? - Education

No. Aluminum is a metal, and magnetic materials are always made of metal, but it's important to note that not all metals are magnetic. The degree of magnetism often depends on the concentration of iron. Therefore, many types of steel are magnetic, but since aluminum is a metal that does not contain iron, it is not magnetic. Recap: Stainless ...

In terms of production volume, aluminium is the leading metal in non-ferrous metallurgy. In particular, the recycling of aluminium-containing residues has strongly increased in recent years and will continue to gain importance in the future. Due to the high affinity of aluminium to oxygen, the oxidation of the molten bath is unavoidable, which leads to the formation of dross on the surface.
