|Aluminum, atomic number 13, atomic mass 26.9, is a lightweight, silver-colored p-block metal. It can be formed into almost any shape. It can be rolled into thick plates for armored tanks or into thin foil for wrappers. It may be drawn into wire or made into cans. Aluminum is the third most abundant element in the earth's crust.
Aluminum has been produced in commercial quantities for just over a century. Pure aluminum is soft and has little strength. Small amounts of elements like copper, magnesium, zinc etc., are added to pure aluminum to give strength.
Aluminum is corrosion-resistant, chemical resistant, strong, a good conductor of heat and electricity, non-magnetic, non-toxic, malleable, ductile, recyclable, and cost-effective.
After iron and steel, aluminum is the most popular metal used for many applications including transportation, vehicle, packaging and food processing, construction, electrical transmission, medicine, and rocket fuel.
Because of its light weight, aluminum is used for making fuel-efficient engines for automobiles. Low weight reduces fuel consumption and emissions. Aluminum is non-toxic and so food can be safely packaged in it. Because it is a good conductor of heat, a lot of cookware is made from aluminum because the energy required to heat it is less than other materials. Aluminum is hygenic and easy to sterilize, so it is used in the production of medical supplies.
