The material

Aluminum is a soft metal, light but resistant, with a silver-gray appearance due to the thin layer of oxidation that forms quickly when it is exposed to air and that prevents corrosion. It weighs about a third of ‘steel or copper; is malleable, ductile and can be worked easily; It has excellent corrosion resistance and durability. It is also non-magnetic, non-sparking ago, and it is the second metal to malleability and sixth for ductility.


The pure aluminum is soft and weak, but it can form alloys with small amounts of copper, magnesium, manganese, silicon and other elements, which have a wide range of useful properties. The alloys used by us belong to families in 2000, 5000, 6000 and 7000 .
