Ferrous Metals
Ferrous metals are pure iron or an alloy which typically consists of iron. The term 'ferrous' has been derived from the Latin term 'ferrum' meaning iron. The most common ferrous alloys are steel. Ferrous metals contain little amounts of other metals or components added, to render it the requisite properties. These metals are magnetic ...
