Why Choose AA1100 Aluminum?
AA1100 is widely used where a lightweight, corrosion-resistant and highly formable aluminum material is required. It is not a high-strength structural alloy, but it performs well in many fabricated sheet-metal and conductivity-related applications.
Excellent Formability
Especially in O temper, 1100 aluminum is suitable for bending, stamping, spinning, drawing and other cold-forming processes.
Corrosion Resistance
Its high aluminum content provides stable natural oxide-film protection in moisture-exposed and mildly corrosive environments.
Good Conductivity
AA1100 provides high thermal and electrical conductivity, making it suitable for heat-transfer and electrical-related components.
Surface Processing
The material can be supplied with mill finish, protective film, brushing, polishing, embossing, anodizing or color coating.

Available Tempers for 1100 Aluminum Sheet and Plate
The most suitable temper depends on the required balance between formability, strength, flatness and final fabrication process.
1100-O
Fully annealed soft temper with excellent ductility. Commonly selected for deep drawing, spinning, bending and severe forming operations.
1100-H12
Quarter-hard temper for light fabrication where more rigidity is needed than O temper while retaining useful forming performance.
1100-H14
Half-hard temper with a practical balance of strength and workability. Often used for panels, trim, signs and general sheet-metal components.
1100-H18
Full-hard temper for applications requiring a more rigid sheet. Typical uses include nameplates, reflectors and rigid formed products.
1100-H22
Strain-hardened and partially annealed temper. Provides a balance between strength and formability for selected fabricated products.
1100-H24
Strain-hardened and partially annealed temper. H24 should not be described as a stabilized temper; exact requirements should follow the applicable standard.
1100-H112
Slightly strain-hardened or as-fabricated temper, typically associated with certain plate and fabricated product requirements.

1100 Aluminum Sheet Surface Finish Options
Surface condition should be selected according to fabrication, appearance, corrosion-resistance and protective requirements. Decorative finishes should be confirmed by sample, color code or approved reference panel.
Mill Finish
Standard industrial finish suitable for general fabrication, insulation, stamping, bending and downstream surface treatment.
Mirror Finish
Used for reflectors, lighting components, decorative panels and selected interior applications. Reflectivity and surface quality should be specified.

Selecting the correct aluminum alloy depends on whether your priority is conductivity, formability, corrosion resistance, strength, machinability or marine performance.
| Alloy | Main Characteristic | Typical Selection Reason |
| 1050 Aluminum | High-purity aluminum with good conductivity and corrosion resistance | Electrical and chemical-related applications requiring high aluminum purity |
| 1060 Aluminum | Higher aluminum content with very good formability and conductivity | Electrical, signage, heat-transfer and general industrial applications |
| 1100 Aluminum | Commercially pure aluminum with excellent formability and corrosion resistance | Cookware, chemical equipment components, reflectors, signage and fabricated sheet parts |
| 3003 Aluminum | Manganese-added alloy with higher strength than 1100 | Roofing, tanks, insulation, HVAC and general fabrication requiring more strength |
| 5052 Aluminum | Higher strength and good marine corrosion resistance | Marine, transportation, fuel tanks, equipment covers and more demanding environments |
| 6061 Aluminum | Heat-treatable alloy with higher strength and good machinability | Structural components, machined parts, frames and engineering applications |
When 1100 Aluminum May Not Be the Best Choice
AA1100 is an excellent option when formability, conductivity and corrosion resistance are the main priorities. However, it has relatively low mechanical strength compared with many aluminum alloys.
- Choose 3003 when you need more strength for general fabrication.
- Choose 5052 when higher strength and marine corrosion resistance are required.
- Choose 6061 when structural performance or machinability is a priority.
- Choose 1060 when higher aluminum purity and conductivity are important.
- Consult the applicable design code for pressure-containing or safety-critical equipment.
Important Note for Pressure and Structural Uses
1100 aluminum may be used for selected chemical-processing equipment components, liners, covers, heat-transfer parts and non-structural fabricated products.
It should not be broadly marketed as a universal pressure-vessel or structural material. Pressure-containing equipment and high-load structural applications must be evaluated according to the applicable design code, material standard, welding procedure, service temperature, operating pressure and corrosion environment.
If your application includes pressure, cyclic loading, marine exposure, elevated temperature or a safety-critical structure, provide the technical specification before selecting the alloy.
