Non-ferrous metals are used in a wide variety of applications. They are light materials well-suited for use where strength is required as in the aircraft or canning industries and as they contain very little iron the non-ferrous metals have a higher resistance to rust and corrosion. They are also non-magnetic which makes them perfect for use in small electronics and for electricalal wiring. Aluminium is the most widely used non-ferrous metal. Aluminium Alloy is commonly known for its use in aluminium foils, beverage cans, transportation, construction, etc. Other non-ferrous metals are also widely used, Copper for electrical wiring, Lead for batteries. Nickel and Tin are used to strengthen and harden the metal alloys and Zinc is used to coat and protect more reactive metals.
