HOW ALLOYING ELEMENTS AFFECT ALUMINIUM ?

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.

Note: 1000, 3000, 5000 and 6000 alloys have good welding characteristics and corrosion resistant. 2000 and 7000 alloys have higher strength and better machinability, but lower weldability and corrosion resistant.
