Aluminium is the most common metallic element found in the earths crust. It is easily formed & machined, it is a superb conductor of electricity, & it can be used in many decorative applications by making use of its high reflectivity.
As a metal it is non toxic, non magnetic and non sparking. Aluminium also has a density of approximately 1/3rd the weight of steel, making it a very light material. Because of this fact, it is widely used in the aerospace industry and other areas where the weight factor is a key design consideration.
Aluminium and the majority of its alloys are highly resistant to most forms of corrosion, and if left untreated the metals natural coating of aluminium oxide provides very effective protection.
Aluminium's natural colour is silver/white, but it can be dyed to virtually any colour by anodizing, which also gives it an additional protective film.
The strength of the aluminium depends upon the purity. 99.996% pure aluminium has a low tensile strength, but by alloying it with other elements, & given suitable heat treatment the tensile strength can reach figures of around 700MPa.
