Aluminum is a lightweight, soft and tough metal, with excelent thermal conductivity, suitable for machining and casting, as well as having excellent corrosion resistance and durability due to the protective layer of oxide.
It can be used in tools, moulds and dies of PET, PP, PVC and ABS, prototype moulds, among others.

Aluminum moulds are most commonly used for small productions, since their machining properties are better than steel, providing a lower cost to the mould.
On the other hand, these are not indicated for large productions due to material wear.


Aluminium Grades – series 5

Magnesium is this series’ biggest alloying element, and manganese is the best hardener. Alloys in this series include 5005, 5052, 5083 and 5086, all of which have great welding characteristics. They are also resistant to marine corrosion, but it depends on limiting the amount of cold work and permitted operating temperatures. Go too high and it becomes susceptible to stress-corrosion cracks.

Aluminium Grades – series 6

The 6 series includes 6061 and 6063, rich in silicon and magnesium which makes them heat treatable. They’re not as strong as 2 and 7 alloys but display good formability, weldability, machinability and corrosion resistance, with medium strength.

Aluminium Grades – series 7

1-8% zinc content and a small amount of magnesium makes the 7m series, which includes grades 7075, 7050, 7049 and 710.0, heat treatable to a high strength. Copper and chromium can also be added in small amounts.

The highest-strength alloys in the series are less resistant to stress-corrosion cracking, but you can achieve more strength, corrosion resistance and fracture toughness by over-aging the temper.

Aluminium Grades – series 8

The 8 series, including 8006; 8111, 8079, 850.0, 851.0 and so on, employs iron and nickel to improve the metal’s strength without losing conductivity.
