Question
Mention the applications of Aluminium.
✓

Answer

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.
  1. Many heat exchangers/sinks and our day to day cooking vessels are made of aluminium.
  2. It is used as wraps (aluminium foils) and is used in packing materials for food items,
  3. 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.
  4. As Aluminium shows high resistance to corrosion, it is used in the design of chemical reactors, medical equipments,refrigeration units and gas pipelines.
  5. Aluminium is a good electrical conductor and cheap, hence used in electrical overhead electric cables with steel core for strength.
