Aluminium Alloys

Series

Main Alloy

Effect on Alloying Elements

1000

Non (99% Alum.)

Unalloyed aluminium is highly corrosion resistant, low strength, workable, conductive, Non-heat-treatable.

2000

Copper Based

Gives strength, hardness, machinability, Heat-treatable

3000

Manganese Based

Adds moderate strength, good workability. Non-heat-treatable

5000

Magnesium Based

Moderate to high strength. Corrosion resistant. Non-heat-treatable

6000

Magnesium & Silicon Based

Increase strength, formability, corrosion resistant. Heat-treatable.

7000

Zinc Based

For greatest strength. Heat-treatable.
