Main Characteristics of 3003 Aluminum Alloy
Mechanical Properties
The tensile strength of 3003 aluminum metal ranges from 142 to 178 MPa, and the conditional yield strength is ≥115 MPa. It has good elongation and hardness of about 40-45 HB, which is higher than that of 1 series pure aluminum, and has better wear resistance and deformation resistance.
Corrosion Resistance
Exhibits exceptional corrosion resistance, comparable to industrial pure aluminum. 3003 aluminum alloy works well against air conditions, fresh water, oceans, food, organic acids, gasoline, and neutral inorganic salt solutions.
Workability
3003 aluminum alloy cannot be strengthened by heat treatment; its mechanical properties can only be improved by cold working. It has high plasticity in the annealed state, good plasticity in the semi-cold-worked state, and low plasticity in the cold-worked state.
Heat Treatment Temper
Common tempers include O (annealed) and H (strain-hardened) series like H12, H14, H16, H18, H22, H24, H26, H28, H112, etc. Different tempers provide varying degrees of strength and ductility.
Application Advantages of 3003 Aluminum Alloy
Lightweight
The density of 3003 aluminum alloy is around 2.73 g/cm³, which is much lower than that of steel. This makes it ideal for weight-sensitive applications.
Corrosion Resistance
Its surface can create a rich oxide film, providing 30% more corrosion resistance in marine climates than 5-series aluminum, making it appropriate for prolonged exposure to hostile environments.
Processing Adaptability
3003 aluminum alloy offers good machinability, making it simple to shear, bend, punch, weld, and perform other manufacturing processes to satisfy complicated production needs.
Cost-effectiveness
Compared to high-strength aluminum alloys, 3003 is less expensive while providing good overall performance, making it a cost-effective material choice.
Applications in Architectural Decoration
3003 aluminum alloy is frequently employed in architectural ornamentation, owing to its high corrosion resistance, decorative appeal, and workability. It is often used for roofing, wall panels, garage doors, and acoustic ceilings.
Roofing Applications
3003 aluminum alloy excels in roofing applications, particularly in the following forms:
Product types include profiled aluminum sheets, corrugated aluminum sheets, and metal roofing systems. These forms offer adequate drainage, good waterproofing performance, and an appealing appearance.
Tempered States: Common tempers include H112, H14, and H24. H112 is suitable for hot-formed goods, as it retains its state after hot processing; H14 and H24, created through cold working, have better strength and hardness, making them suitable for roofing that requires structural integrity.
