Basic Characteristics of 3003 Aluminum Alloy

Material Classification
  • Series: Aluminum-manganese alloy(3000 series)
  • Heat Treatability: Non-heat-treatable; strengthened via cold working (e.g., rolling, stretching)
  • Alias: Rust-proof aluminum sheet and plate (due to excellent corrosion resistance)

Core Advantages

  • Strength: ~20% higher than pure aluminum 1100 series (Tensile strength: 110–150 MPa)
  • Corrosion Resistance: Excellent atmospheric/marine corrosion resistance; suitable for humid/chemical environments.
  • Workability:
    • Superior formability (deep drawing, spinning, bending).
    • Good weldability (TIG, resistance welding, brazing).
    • Compatible with anodizing, spraying, and other surface treatments.
  • Lightweight: Density: 2.73 g/cm³ (~1/3 of steel).
