Information on Materials: Aluminium, the Shiny Wonder Metal!

Aluminium is the most abundant metal in the earth's crust, yet it had to wait until the 19th century to enter an industrial phase.
Today, its large production makes it the leading non-ferrous metal.
wikipedia of aluminium The production of aluminium begins with the extraction of alumina from bauxite, the electrolysis of which then leads to aluminium.
This metal is malleable and highly resistant to oxidation, but it is these properties of lightness and inalterability
that make it so attractive in sectors such as aeronautics and transport.
The addition of metals that form solid solutions with aluminium gives it mechanical strength comparable to that of hardened steels.
Whether they are the main additive, a secondary additive or even an impurity,
their presence has a considerable influence on the characteristics of the final alloy,
whose density remains three times lower than that of steel.

Here is an article on an almost similar subject, cast aluminium alloys. In order to improve its properties, the thermal and mechanical treatments during its manufacture,
structural hardening, quenching, tempering, maturation, work hardening, are chosen and retained according to the desired performances.
The use and transformation of aluminium can easily benefit from all the wrought and foundry methods.

as well as the relative ease of welding any homogeneous assembly made of light alloys.
