Uses of Metals
Metals and their alloys with other metals find extensive use in our daily life. Iron, copper, aluminium, silver, gold, etc., are extensively used.
- Iron or steel is used for the construction of bridges, houses, automobile parts, etc. Stainless steel, an alloy of iron is used for utensils, spoons, plates, etc., Iron mixed with concrete, is known as reinforced concrete. It is very strong and is used in the construction of bridges and houses.
- Aluminium is a light metal and a good conductor of electricity. Aluminium wires are used as overhead wires instead of copper. Aluminium alloys are light and strong and hence used to construct aeroplane parts. Aluminium foils are used to wrap food stuff, medicines and chocolates.
- The liquid metal mercury is used in making thermometers.
- Copper and aluminium metals are used to make wires to carry electric current. Copper bottomed utensils are used in houses. Copper metal is used as electrodes and wires are used in heaters.
- Sodium, titanium and zirconium metals are used in atomic energies and space science projects.
- Zinc is used for galvanising iron to protect it from rusting.
Silver and gold are extensively used in making ornaments.
