METALS A material that can be in a solid or a liquid state and usually has a lot of electrical conductivity, one of the material properties. A good example of a metal it's gold. They are classified in two types ferrous and non-ferrous . Types of Metals 1.FERROUS METALS: they contain iron . Ferrous metals can be picked up by a magnet,they are not resistant to rusting. Some examples of ferrous metals are: a) Cast Iron : used to make frying pans. The principal properties of cast iron are: - Resistance to corrosion - Hardness - Strength b)Carbon Steel: used in tools. The proerties of carbon steel change depending on the number of carbon that contains. The general properties that nearly all share is: - Strength and ductility (as higher is the number of carbon content the strength grows and ductility is lower.) -Strong metal - Resists to compression c)Mild Steel: used in building car bodies, gat
