Types of aluminium

We always supply select material
In the process of collecting the various types of aluminium scraps that we manage daily, we pay the utmost attention to preventing contamination of the different alloys we collect.
The aluminium collection area we have is very large and every type of alloy has a special dedicated storage space.
The controls and processing we implement are to prevent any impurities of the material collected. Customers who buy from us always have the certainty that they will receive a product compliant with their order.

Below is a classification table of the various types of aluminium alloys.

The alloys consist of aluminium and a series of other alloying metals.
In the table the highlighted item along with the aluminium (i.e. Al-Cu or Al-Mn) is the substance with the higher percentage compared to the others (obviously excluding aluminium, which is always the main component).
Cu
Increased mechanical resistance and hardness proportional to the quantity of Cu
Improves workability of machine tools
Decreases corrosion resistance
Mn
Increases mechanical resistance and resilience
Improves ductility
Si
Increases mechanical resistance
Strong decrease in workability of machine tools
Slight decrease in corrosion resistance
Mg
Increases mechanical resistance and hardness
Improves workability of machine tools, ductility and corrosion resistance
Zn
Increases mechanical resistance and deformability
Strong decrease in corrosion resistance
Increased fragility to heat
Makes the alloy self-tempering
Fe
Increases mechanical properties, even to heat
Reduces fragility to heat
Enhances die-casting detachment
