Keyword - Metal - Ferrous

Definition Metal - Ferrous includes iron and all its alloys, such as steel. Ferrous metals are magnetic to some extent, depending on the presence or absence of non-ferrous plating, etc. Ferrous metals "rust" when exposed to moisture and air, producing a reddish colour. Rust is not magnetic and may greatly reduce the degree of magnetism of a piece. Rust often becomes very thick and obscures the original form of the object.
