non-ferrous are The metals other than iron and alloys that do not contain an appreciable amount of ferrous (iron) are known as non-ferrous metals. A distinguishing feature of non-ferrous metals is that they are highly malleable

ferrous metals are Ferrous Metals mostly contain Iron. They have small amounts of other metals or elements added, to give the required properties. Ferrous Metalsare magnetic and give little resistance to corrosion.
