AA 3003 (EN AW-3003) Aluminum Alloy Coil
Leading 3003 ALUMINUM Alloy Coil MANUFACTURER IN CHINA
AA 3003 (EN AW-3003) is the premier choice for applications that require excellent formability and resistance to atmospheric corrosion. As the most widely used general-purpose aluminum alloy, its addition of manganese increases its strength by about 20% over pure aluminum grades. This non-heat-treatable alloy provides a versatile, cost-effective, and highly reliable solution for a wide range of manufacturing, industrial, and architectural projects, delivering both outstanding performance and a smooth, clean finish that withstands the test of time.

Characteristics of 3003 Aluminum Alloy
- Excellent Corrosion Resistance: Offers excellent resistance to atmospheric conditions and many chemical environments, ensuring long-term durability.
- Superior Formability: This highly ductile material can be easily deep drawn, spun, bent, and fabricated into complex shapes without cracking.
- Good Weldability: Can be readily welded using all standard welding techniques, making it versatile for fabricated assemblies.
- Moderate Strength: The addition of manganese provides approximately 20% more strength than pure aluminum, making it a robust general-purpose alloy.
- Non-Heat-Treatable: Strength is enhanced through cold working (strain hardening), designated by H-tempers (e.g., H14, H18).
- Lightweight & Strong: Provides a fantastic combination of low density with moderate strength, ideal for a wide range of applications.
- Excellent Thermal Conductivity: Its ability to transfer heat efficiently makes it a preferred material for heat exchangers, cookware, and chemical equipment.
- Versatile & Aesthetic Finish: Delivers a smooth, clean surface that can be easily finished, painted, or anodized for decorative and architectural uses.
