ㆍ1000 Series (Pure Aluminum)
99% Al minimum. Excellent workability and conductivity but low strength. Non-heat treatable.
ㆍ2000 Series (Al-Cu-Mg)
Added Copper for high strength. Includes Duralumin (A2017). High mechanical properties but low corrosion resistance and weldability.
ㆍ3000 Series (Al-Mn)
Added Manganese for higher strength than pure Al. Used in cans and architectural materials like A3003.
ㆍ4000 Series (Al-Si)
Added Silicon for low thermal expansion and wear resistance. Used for welding fillers and heat-resistant parts.
ㆍ5000 Series (Al-Mg)
Added Magnesium. Strongest non-heat treatable alloy with excellent weldability. A5052 is representative.
ㆍ6000 Series (Al-Mg-Si)
Structural alloy with good strength and corrosion resistance. Popular for extrusions and mechanical joints.
ㆍ7000 Series (Al-Zn-Mg)
Added Zinc and Magnesium. Highest strength among Al alloys. Includes A7075 (Extra Super Duralumin) for aerospace applications.
