Applications of Aluminium
Aluminium is an alloying mineral with the chemical symbol Al within it, together with the atomic number 13 together with a triple bond between the aluminium and oxygen. Aluminium has a high density lower than all other metals, at about one-fourth that of steel, which makes it an excellent insulator. It forms a protective film of oxide on the outside, especially when subjected to air, and has a very good affinity for oxygen.
When you rub your hands with aluminium your hands will sweat, this is because of the special properties of aluminium. If you put aluminium dust on your skin it burns your skin immediately, but it won’t burn your fur or hair. Aluminium in the making of modern aircraft is used extensively, as it has low conductivity properties, so that the fuel does not boil off when subjected to high temperatures, thus keeping the plane flying.
Aluminium is also widely used in the making of tubes and pipes for plumbing, electronics and electrical work, due to the fact that it is soft and ductile and these are materials that can bend and flex without damage easily. There are some alloys which are made from pure aluminium, called pure aluminium alloys.
This material is stronger and harder than other aluminium alloys, but is heavier than lead. In the process of making pipes for plumbing the Aluminium pipe insulation is often used in place of the liner within the pipes. As well as this the tubes may be painted with a paint designed to protect them from the corrosive properties of water, and also from the corrosive effects of corrosion. Aluminium is perfect for shaping using Tapping Machines like the ones from Cotswold Machinery Sales
