Key Features & Advantages
- Excellent Corrosion Resistance: The dense oxide film naturally formed on the surface provides strong resistance to atmospheric, freshwater, seawater, organic acids and neutral salt solutions, ideal for humid and corrosive working environments.
- Superior Processing Performance:
- Formability: High plasticity in O-state (annealed), suitable for deep drawing, bending and stamping to create complex-shaped components.
- Weldability: Excellent compatibility with argon arc welding and resistance welding, ensuring firm and reliable welded joints.
- Lightweight: Density of 2.7g/cm³, approximately 1/3 of steel, effectively reducing structural weight and transportation costs.
- Moderate & Reliable Mechanical Properties:
- Tensile Strength: 120-160 MPa
- Yield Strength: ≥85 MPa
- Elongation: ≥20% (O-state)
- Cost-Effective & Eco-Friendly: Lower cost than heat-treatable aluminum alloys; 100% recyclable, aligning with green manufacturing and low-carbon development trends.
Common Grades & States
- O (Annealed): Softest state, optimal ductility for complex forming.
- H14/H24 (Half-Hard): Balanced strength and ductility for general structural use.
- H18/H28 (Full-Hard): Highest strength for load-bearing components.
- H112: Suitable for hot-formed parts.
Wide Applications in Engineering & Manufacturing
- Transportation: Automotive fuel tanks, oil pipelines, ship storage tanks, deck components.
- Chemical Industry: Storage tanks, reaction vessels, corrosion-resistant pipelines, heat exchangers.
- Construction & Decoration: Corrugated roof panels, anti-rust wall panels, curtain wall components.
- General Manufacturing: Kitchenware, food processing equipment, ventilation ducts, low-load rivets.
- Energy & Electrical: Radiators, transformer casings, battery enclosures.
