. Applications of metals . . Applications of Al Aluminium is the most abundant metal and is a good conductor of electricity and heat.
It also resists corrosion. The following are some of its applications. Â Many heat exchangers/sinks and our day to day cooking vessels are made of aluminium. Â It is used as wraps (aluminium foils) and is used in packing materials for food items, Â Aluminium is not very strong, However , its alloys with copper, manganese, magnesium and silicon are light weight and strong and they are used in design of aeroplanes and other forms of transport.
 As Aluminium shows high resistance to corrosion, it is used in the design of chemical reactors, medical equipments,refrigeration units and gas pipelines.  Aluminium is a good electrical conductor and cheap, hence used in electrical overhead electric cables with steel core for strength. . .
Applications of Zn  Metallic zinc is used in galvanising metals such as iron and steel structures to protect them from rusting and corrosion.  Zinc is also used to produce die-castings in the automobile, electrical and hardware industries  Zinc oxide is used in the manufacture of many products such as paints, rubber, cosmetics, XII U1 Metallurgy - XII U1 Metallurgy - - - - - pharmaceuticals, plastics, inks, batteries, textiles and electrical equipment. Zinc sulphide is used in making luminous paints, fluorescent lights and x-ray screens.  Brass an alloy of zinc is used in water valves and communication equipment as it is highly resistant to corrosion.
. . Applications of Fe  Iron is one of the most useful metals and its alloys are used everywhere including bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels.  Cast iron is used to make pipes, valves and pumps stoves etc...
 Magnets can be made from iron and its alloys and compounds.  An important alloy of iron is stainless steel, and it is very resistant to corrosion. It is used in architecture, bearings, cutlery, surgical instruments and jewellery. Nickel steel is used for making cables, automobiles and
