Aluminum Alloy Grades, Status, Properties, and Applications

Aluminum Alloy Grades

  1. 1000 Series: Pure aluminum with excellent corrosion resistance and high thermal and electrical conductivity.
  2. 2000 Series: Copper is the main alloying element, offering high strength and good machinability.
  3. 3000 Series: Manganese is the main alloying element, providing good corrosion resistance and moderate strength.
  4. 4000 Series: Silicon is the main alloying element, improving wear resistance and reducing the coefficient of thermal expansion.
  5. 5000 Series: Magnesium is the main alloying element, offering good corrosion resistance and high strength.
  6. 6000 Series: Silicon and magnesium are the main alloying elements, providing good mechanical properties and corrosion resistance.
  7. 7000 Series: Zinc is the main alloying element, offering the highest strength among aluminum alloys.
  8. 8000 Series: Other elements, such as lithium, providing specialized properties for specific applications.




  1. Aerospace: High-strength alloys (e.g., 7075) are used in aircraft structures and components due to their excellent strength-to-weight ratio.
  2. Automotive: Alloys like 6061 and 6063 are used in car frames, engine components, and wheels to reduce weight and improve fuel efficiency.
  3. Construction: 5000 and 6000 series alloys are used in building facades, window frames, and structural components for their durability and corrosion resistance.
  4. Marine: 5000 series alloys are favored for shipbuilding and offshore structures due to their excellent corrosion resistance in seawater.
  5. Electronics: Pure aluminum (1000 series) and certain 6000 series alloys are used in heat sinks, wiring, and casings for their conductivity and lightweight properties.
  6. Consumer Goods: Used in household appliances, sporting goods, and packaging materials for their formability and aesthetic appeal.
