All About Aluminium

Aluminium is an extremely light-weight metal and it is the most commonly used in construction. It is also the strongest metal in its pure form. Aluminium is a soft, ductile element having the symbol 13 on its atomic number and atomic symbol Al. Aluminium has a low density similar to those of stainless steel, about one third of that of pure steel. When exposed to air, it forms a protective coating of oxide on the exterior surface, which makes aluminium ideal for use as protection from damage by fire.

Aluminium is formed by the reaction between aluminum and carbon dioxide. This occurs when the metal is exposed to high temperatures; hence the name ‘hot’ aluminum. The other forms are usually referred to as cooled aluminum (caustic aluminum) or hydrated aluminum (caustic aluminum chloride). The main difference between the two is that aluminum chloride is not as toxic as the former. The other main difference between the two is that hydrated aluminum does not bond with water. Other common materials that are made of aluminum are bath tubs, shelves, automotive parts and pipes.

Aluminum has very high strength-to-weight and tensile strength which is why it is used in many industries including aviation. It is the perfect metal to be shaped using Tapping Machines like those from Cotswold Machinery Sales. It can be taken in sheets and moulded into a variety of shapes and joined together to create a variety of structures.
