Anodized aluminum sheet 1050 1060 1100 HO H12 Mill
Anodized aluminum sheets in grades 1050, 1060, and 1100 with HO and H12 tempering conditions from the mill are widely esteemed for their excellent corrosion resistance, superior surface finish, and versatile mechanical properties.
Anodized aluminum sheets refer to aluminum plates that have undergone an electrochemical process, anodization, which thickens the natural oxide layer on the surface. This protective layer improves corrosion resistance, surface hardness, and wear properties, making the sheets suitable for various commercial, industrial, and decorative applications.
The alloys 1050, 1060, and 1100 represent near-pure aluminum grades, distinguished mostly by their slight variations in purity and impurity limits:
| Alloy | Typical Aluminum Content (%) | Notable Properties |
|---|---|---|
| 1050 | ≥ 99.5 | Excellent ductility, high electrical conductivity, good corrosion resistance |
| 1060 | ≥ 99.6 | Higher purity with improved electrical & thermal conductivity |
| 1100 | ≥ 99.0 | Superior corrosion resistance and formability |
The temper conditions, HO (annealed) and H12 (strain-hardened to a quarter hard), control the mechanical strength and workability of the sheets.
Features and Functions
Enhanced Surface Durability from Anodizing
Anodizing transforms the aluminum surface into a hard, non-conductive layer resistant to abrasion and corrosion. This protection layer extends the lifespan and performance of components fabricated from these sheets.
Superior Electrical and Thermal Conductivity
Grades 1050, 1060, and 1100 are among the highest conductivity commercially available aluminum alloys, suitable for electrical conductors or heat exchangers.
Excellent Workability
The expressed softness of these alloys in HO temper makes them highly formable and easy to shape. In H12 temper, modest stiffness is achieved while maintaining workability - a balance for applications needing shaped parts with moderate strength.
Common Industry Applications
- Electrical Busbars and Conductors: Exploiting high electrical conductivity.
- Architectural Cladding and Facade Elements: Utilizing high corrosion resistance and the aesthetic quality of anodization.
- Packaging and Food Industry: Safe, corrosion-resistant surfaces for foil, foils, and trays.
- Household and Kitchenware: Combining non-toxic anodized finish and ductility for appliances and utensils.
- Signage and Decorative Panels: Durable, stylish anodized surface ideal for advertising and displays.
