EN AW-1050A H111 Aluminum Plate Description
What is EN AW-1050A H111 Aluminum Plate?
EN AW-1050A is a commercially pure aluminum alloy containing at least 99.5% aluminum. The "H111" temper indicates that the material has undergone a specific strain-hardening process. Unlike the fully annealed "O" temper, H111 has received a slight amount of work hardening during shaping processes (like stretching or leveling), but not enough to be classified as a standard H11 temper.
Key characteristics of the H111 temper include:
- Slightly higher tensile and yield strength compared to the fully soft O temper.
- Retains extremely high elongation and formability.
- Will not crack during deep drawing, tight bending, or spinning processes.
- Provides a highly stable flat surface, making it easier for automated cutting and welding.
EN 1050A Aluminium Plate Chemical & Mechanical Properties
To guarantee the corrosion resistance and conductivity of your final products, the chemical composition and mechanical stability must be strictly controlled.
The high purity of 99.5% minimum aluminum is what gives this grade its working characteristics. We strictly control iron (Fe) and silicon (Si) impurities to prevent brittle spots.
| Element | Content Limit (%) |
| Aluminum (Al) | ≥ 99.5 |
| Silicon (Si) | ≤ 0.25 |
| Iron (Fe) | ≤ 0.40 |
| Copper (Cu) | ≤ 0.05 |
| Manganese (Mn) | ≤ 0.05 |
| Magnesium (Mg) | ≤ 0.05 |
| Zinc (Zn) | ≤ 0.05 |
| Titanium (Ti) | ≤ 0.05 |
A1050 H111 Aluminum Mechanical Properties
The H111 temper strikes a balance between softness for bending and enough rigidity to handle fabrication without deforming easily.
| Property | Value Range |
| Tensile Strength (Rm) | 65 – 95 MPa |
| Yield Strength (Rp0.2) | ≥ 30 MPa |
| Elongation (A50mm) | ≥ 20% |
| Brinell Hardness (HB) | ~ 20 |

Applications for 1050 Pure Aluminum Plate
Why do engineers specifically request the 1050 aluminum sheet H111? It comes down to three main industrial environments: highly corrosive chemical zones, high-current electrical systems, and complex forming manufacturing.
1. Chemical Storage Tanks and Pressure Vessels
In the chemical industry, materials frequently contact nitric acid, hydrogen peroxide, and organic acids. 1050A H111 is highly resistant to chemical attacks because its 99.5% purity forms a dense, uninterrupted oxide layer on the surface.
Why H111? When manufacturing large cylindrical tanks, the aluminum plates must be rolled. The H111 temper ensures the plate rolls smoothly without work-hardening too fast, preventing micro-cracks during fabrication. It also offers excellent TIG and MIG weldability, ensuring leak-proof joints.
2. Electrical Conductors and Busbars
For electrical engineering, conductivity is money. 1050A aluminum offers a minimum electrical conductivity of 60% IACS. It is widely used to manufacture stamped busbars, transformer windings, and heavy-duty switchgear components. It is significantly lighter and cheaper than copper while delivering reliable current transmission.
3. Food Industry Containers and Heat Exchangers
Because it contains no toxic alloying elements, 1050A is food-grade safe. Its excellent thermal conductivity makes it standard for industrial heat exchanger fins and cooling plates.
Case Study: Reducing Scrap in Busbar Manufacturing
A electrical components manufacturer was buying standard 1219mm x 2438mm sheets of 1050A H14 locally, then slitting them down for busbars. They faced two problems: the H14 temper sometimes cracked during 90-degree bending, and the standard sizes resulted in a 14% material scrap rate.
They switched to GNEE as their 1050A aluminum plate supplier. We recommended the H111 temper to completely eliminate bending cracks. More importantly, we supplied custom-slit widths of exactly 150mm and 200mm direct from our factory. The client's scrap rate dropped to under 2%, and their fabrication time was reduced by 30%.
1050A H111 vs Other Tempers (H14, H18, O)
Selecting the wrong temper can ruin a production run. Here is a direct comparison to help you choose the right EN AW-1050A aluminum plate for your project.
| Temper | Processing Method | Strength | Ductility | Best For |
| 1050 H111 | Slightly strain-hardened | Medium-Low | Very High | Deep drawing, tight bending, general fabrication. |
| 1050 O | Fully annealed (soft) | Lowest | Highest | Extreme deep drawing, spinning, foil production. |
| 1050 H14 | Half-hardened | Medium | Medium | Flat panels, stamping, low-stress bending. |
| 1050 H18 | Fully hardened | Highest | Lowest | Rigid structural parts, applications requiring no bending. |
Summary: Choose H111 if you need the formability of the O temper but require the plate to hold its flat shape better during handling and laser cutting. Choose H14 if you need more structural rigidity and only plan to do shallow stamping.
