Composition & Properties of 3003 Alloy Aluminum

• Alloy: The 3003 alloy belongs to the wrought aluminum–manganese family. Primarily aluminum with manganese as the main alloying element (1.0–1.5%), enhancing corrosion resistance without compromising workability.

• Non-heat-treatable: Strength is achieved through cold working rather than heat treatment.

• Moderate Strength: Balanced tensile strength and ductility, suitable for medium-duty applications.

• Excellent Corrosion Resistance: Withstands atmospheric and chemical corrosion, making it perfect for marine, chemical, and food-processing environments.

• Good Formability: Easy to bend, draw, and shape into complex forms.

• Good Weldability: Compatible with common welding methods, including MIG, TIG, and resistance welding.

Key Characteristics of 3003 aluminum

• Workability: Can be cold worked to increase strength without losing ductility.

• Surface Finish: Accepts anodizing and coating for enhanced appearance and protection.

• Versatility: Suitable for a wide range of end uses, from industrial equipment to household items.

Common Applications of 3003 Aluminum Sheets & Coils

• General Sheet Metal Work: Roofing, siding, ductwork, and enclosure panels.

• Chemical Equipment: Tanks, piping, and process equipment requiring corrosion resistance.

• Cookware & Utensils: Pots, pans, and food-handling tools thanks to non-toxic and clean surface properties.

• Decorative Components: Trim panels, signage, and architectural features.

• Pressure Vessels: Storage containers for liquids and gases.

• Piping & Tubing: Fluid transportation systems in multiple industries.

• Hardware: Builder’s tools, mechanical components, and fastening systems.

• Ice Cube Trays: Commonly used for their resistance to low temperatures and moisture.

Advantages Over Other Alloys

• Stronger than 1100 Aluminum: Offers approximately 20% higher strength while maintaining excellent corrosion resistance.

• Different from 5052 Aluminum: While 5052 offers higher tensile strength, 3003 alloy aluminum remains the more cost-effective and versatile choice for general applications.

• Cost-Effective: Provides an optimal balance of performance and price, ideal for large-scale projects.
