Aluminum Alloy 3003

Aluminum alloy 3003 is a highly versatile and cost-effective alloy known for its excellent corrosion resistance, malleability, and lightweight properties. It is one of the most widely used aluminum alloys in various applications, from architectural and construction projects to food processing and automotive components. This alloy is primarily composed of aluminum (Al), with manganese (Mn) as the primary alloying element, giving it its notable strength and resistance to corrosion.

Its medium-strength characteristics and excellent formability make it ideal for manufacturing parts that require a good strength-to-weight ratio and resistance to harsh environments, including marine and outdoor conditions.

Material Composition and Properties

Aluminum alloy 3003 is made up of primarily aluminum (99.0%), with manganese (Mn) (1.0-1.5%) being the principal alloying element. The manganese improves the alloy’s strength and enhances its resistance to corrosion, making it a popular choice for environments that involve exposure to moisture and chemicals.

Key Mechanical and Physical Properties of Aluminum Alloy 3003:

• Tensile Strength: 110–150 MPa

• Yield Strength: 55–95 MPa

• Hardness: 40–50 HB

• Density: 2.73 g/cm³

• Thermal Conductivity: Excellent for heat exchange applications

• Corrosion Resistance: Excellent, particularly in industrial and marine environments

• Elongation at Break: 20–30%

• Fatigue Strength: Moderate resistance to fatigue

• Formability: High, can be easily formed, bent, and stamped

Aluminum 3003 is also highly recyclable, making it an eco-friendly choice for a wide range of industrial applications.
