Aluminum is the third most common element found in the earth’s crust. Aluminum compounds make up 8% of the earth’s crust and are present in most rocks, vegetation and animals. In its natural state it is found in many silicates (feldspars, plagioclases and micas). As a metal, it is extracted only from the mineral known by the name of bauxite, and is first transformed into alumina using the Bayer process and then into metallic aluminum through electrolysis.
Aluminum is a soft (Mohs scale: 2-3-4) and malleable material. In its pure state, it has a tensile strength limit of 160-200 N/mm² (160-200 MPa). All of which makes this element suitable for the manufacture of electrical cables and thin sheets, but not as a structural element. It is alloyed with other metalsin order to improve these properties, which enables it to be used in casting and forging operations, in addition to the extrusion of the material. It is also used as weld metal in this form.
