Anodized aluminum sheet 1100 1060 2024 3003 6061 8011

10/06 2025 Leo

Anodized aluminum sheets are aluminum alloy sheets that have been electrochemically treated to create a durable, corrosion-resistant oxide layer on the surface. This process significantly enhances the material's longevity, surface hardness, aesthetic appeal, and corrosion resistance while retaining the inherent lightweight and versatile qualities of aluminum.

Alloy	Series	Typical Use	Characteristics
1100	1xxx	Decorative and architectural	Excellent corrosion resistance, high purity (≥99%), low strength
1060	1xxx	Electrical and chemical equipment	Very good formability and corrosion resistance, >99.6% aluminum content
2024	2xxx	Aerospace, military	High strength and fatigue resistance, not ideal for high corrosion environments
3003	3xxx	Roofing, siding, cooking utensils	Good corrosion resistance moderate strength, good workability
6061	6xxx	Structural and transportation	Well-balanced mechanical properties, good corrosion resistance
8011	8xxx	Packaging and household products	Good workability with corrosion resistance against atmospheric effects

Advantages of Anodized Aluminum Sheets

Enhanced Corrosion Resistance: Exceptional resistance to atmospheric chemicals and saltwater.
Improved Surface Hardness: Anodic oxide is 3-5 times harder than raw aluminum, protecting against scratches and wear.
Aesthetic Versatility: Available with a matte, glossy, or colored finish for architectural friendliness.
Thermal and Electrical Insulation: Anodized layer acts as an electrical insulator and improves thermal emissivity.
Environmental Compatibility: Non-toxic surface suitable for food contact and medical applications.
Easy Maintenance: Smooth anodized surfaces are easier to clean and resist stains.
