non-ferrous metals

One method of classifying metals is by their content, and one common division is into ferrous metals and non-ferrous metals. The term ferrous is derived from the Latin "Ferrum" which means "containing iron", thus ferrous metals contain iron and non ferrous metals do not. Ferrous metals may be pure iron, like wrought iron, or they may be alloys of iron and other elements. Steel, being an alloy of iron and carbon, would therefore be a ferrous metal.
