Introduction of 1100 Aluminum Sheet
The 1100 aluminum plate corresponds to grades such as Al99.0 (ISO) and EN AW-1100, containing at least 99% aluminum. It offers excellent corrosion resistance, strong electrical and thermal conductivity, and good formability. These properties make it suitable for charging pile components, automotive heat sinks, and various sheet metal applications. With pressure forming and stamping processes, 1100 aluminum is widely used in the new energy vehicle industry.
Advantages of 1100 Aluminum Sheet
- Excellent electrical conductivity: The high aluminum content provides active electrons, giving aluminum strong current-carrying capability.
- Corrosion resistance: A natural oxide layer forms on the surface, protecting the metal from further oxidation. Anodizing can further enhance corrosion resistance.
- Great ductility: Although pure aluminum has relatively low strength, it offers outstanding formability and is easy to process.
- Wide range of applications: With different processing methods, aluminum can achieve various mechanical properties to meet the needs of many industries. Most importantly, it remains a cost-effective material.

Mechanical Properties of 1100 Aluminum Sheet by Temper
You might be wondering about the specific differences in mechanical properties of 1100 aluminum plates in different states (such as O, H12, and H24). I’ve compiled a comparison of mechanical properties data and application instructions for these different states.
| Temper |
Typical Tensile Strength UTS (MPa) |
Typical Yield Strength Rp0.2 (MPa) |
Typical Elongation (%) |
Notice |
| O |
75–105 |
20–35 |
15–25% |
Maximum ductility; ideal for deep drawing and complex forming. |
| H12 |
80–110 MPa |
36–92 |
10–15% |
Light strain hardening; maintains good bending and drawing workability. |
| H14 |
95–130 |
95–110 MPa |
6–12% |
Most common commercial temper; balanced strength and formability. |
| H18 |
Up to ~160 MPa |
Higher than H14 |
Low |
Full-hard condition; low ductility; used for applications requiring flatness, rigidity, or higher strength. |
| H24 |
90–140 MPa |
Medium |
Medium (better than H18, lower than O) |
Balanced option between strength and formability; easier to process than full-hard. |
Applications of 1100 Aluminum Sheet
1100 aluminum sheet is widely used in:
- Food and Chemical Processing Equipment
1100 aluminum exhibits excellent stability in acidic and alkaline environments, making it a common metallic material for manufacturing components such as storage tanks, mixing vessels, piping systems, and processing equipment used in the food, chemical, and pharmaceutical industries.
- Heat Exchangers and Cooling Components
With excellent thermal conductivity, it is frequently used to manufacture air conditioner radiators, heat sink fins, and cooling equipment for heat exchange.
- Packaging and Bottle Caps
This alloy is stamped into bottle caps, packaging seals, and products requiring high formability.
- New Energy Vehicle Applications
Due to high requirements for formability and stability, it is used to manufacture charging pile components, battery casings, and precision metal parts for the electric vehicle and electronics industries.
- Household and Commercial Cookware
1100 alloy, after deep drawing, is widely used in the manufacture of cookware, kitchen utensils, and metal baking pans.
