EN AW 1050A H12 Aluminum Sheet Description
What is EN AW 1050A H12 Commercial Pure Aluminum Plate?
EN AW 1050A is a non-heat-treatable aluminum alloy in the 1000 series, known for its high purity and excellent corrosion resistance.
H12 temper indicates strain-hardened aluminum with partial annealing, providing moderate strength and improved formability compared to fully hard tempers.
This combination of material grade and temper creates a highly workable metal sheet. It does not rely on heat treatment to gain its strength. Instead, the H12 condition is achieved through cold rolling, making it strong enough to hold its shape but soft enough to be bent and formed without cracking.
Understanding EN 485-2 & EN 485-4 Standards for 1050A Alloy Sheets
For European and international engineering projects, material compliance is strictly required. Our 1050A H12 aluminum panels are manufactured and tested in strict accordance with the EN 485 series standards.
Standards: EN 485-2 / EN 485-4
- EN 485-2: defines the mechanical properties, including tensile strength, yield strength, and elongation limits for aluminum sheets.
- EN 485-4: specifies dimensional tolerances for aluminum sheets, covering thickness, width, length, and flatness tolerances.
By meeting these standards, buyers are guaranteed consistent material performance and exact physical dimensions, which is crucial for automated stamping, cutting, and large-scale manufacturing processes.
Chemical Composition of 1050A Aluminum Plain Sheet
The purity of 1050A aluminum determines its excellent electrical conductivity and corrosion resistance. As a commercially pure alloy, it contains strict limits on alloying elements.
| Element | Content (%) |
| 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) | ≤ 0.07 |
| Titanium (Ti) | ≤ 0.05 |
Note: The 99.5% minimum aluminum base is what classifies this as a 1000-series alloy, ensuring it remains highly ductile and resistant to atmospheric and chemical corrosion.
Mechanical Properties of 1050A H12 Aluminum Panel
1050A H12 aluminum sheet offers moderate strength with excellent ductility. This makes it an ideal material for deep drawing, spinning, and bending applications.
| Property | Value |
| Tensile Strength (Rm) | 70 – 105 MPa |
| Yield Strength (Rp0.2) | ≥ 35 MPa |
| Elongation (A50mm) | ≥ 12% |
| Hardness (Brinell) | Approx. 23 HBW |
The H12 temper (1/4 hard) provides a balanced mechanical profile. It is stiffer than the fully annealed O temper, preventing unwanted deformation during handling, yet it maintains a minimum 12% elongation rate, allowing for complex sheet metal fabrication.
Core Characteristics of 1050A H12 Aluminum Metal Sheet
- Excellent corrosion resistance
- High electrical conductivity
- Good formability
- Lightweight
- Easy to process
Typical Applications of the 1050A H12 Aluminum Flat Sheet
Due to its high purity and workability, the EN AW 1050A H12 aluminum plate is widely utilized across multiple industries. It is not designed for heavy structural load-bearing, but rather for environments requiring chemical stability and electrical efficiency.
- Electrical conductors: Busbars, transformer windings, and cable shielding due to its high conductivity.
- Chemical equipment: Storage tanks, piping, and containers handling corrosive chemicals.
- Reflectors and lighting: Lamp reflectors and architectural lighting fixtures because of its excellent reflective properties when polished.
- Sheet metal fabrication: General casing, covers, and housings for machinery and electronics.
- Decorative panels: Architectural exterior and interior cladding, ceilings, and signage that require a clean, bright metal finish.
- Heat exchangers: Radiator fins and cooling components where thermal conductivity is necessary.

Processing and Fabrication Guide for 1050A Alloy
For manufacturers planning to process this material, the EN AW 1050A H12 behaves predictably under standard workshop conditions.
- Welding: It has excellent weldability. It can be easily joined using TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding methods. Standard pure aluminum filler wire (like 1070 or 1050) is recommended.
- Bending and Forming: The H12 temper allows for standard 90-degree bends with a very tight inner radius. It is highly suitable for cold forming operations without the need for intermediate annealing.
- Machinability: Due to its softness, machinability is rated as poor to fair. Sharp tools, high speeds, and adequate lubrication are required to prevent the metal from sticking to the cutting tools.
Packaging and Export Shipping Standards
Our EN AW 1050A sheet supplier operations adhere to strict export packaging standards.
- Moisture Protection: Sheets are wrapped in high-density waterproof paper and plastic film to prevent oxidation or water stains during ocean freight.
- Palletizing: Products are secured on fumigated wooden pallets or wooden cases, strapped with steel or heavy-duty PET bands.
- Edge Protection: Rigid edge protectors are applied to prevent deformation of the sheet corners during loading and unloading.
- Identification: Each pallet includes clear labeling with alloy grade, temper, dimensions, standard (EN 485-2/4), and heat numbers for full traceability.
