Steel is iron and a little carbon.. Iron is the most common impurity found in aluminum. It has a high solubility in molten aluminum and is therefore easily dissolved at all molten stages of production. The solubility of iron in the solid state is very low (~0.04%) and therefore, most of the iron present in aluminum over this amount appears as an intermetallic second phase in combination with aluminum and often other elements.. Alloys are often described by the atomic percentage or weight percentage of the constituent elements be sure to state which!
