1050A Aluminium Sheet – Cost-Effective Pure Aluminium Plate for General Engineering
Searching for a reliable pure aluminium sheet with excellent surface quality and easy fabrication?
GNEE supplies high-quality 1050A aluminium sheet and aluminium plate, meeting both national and international standards for general engineering and industrial applications.
What Is 1050A Aluminium Sheet?
1050A aluminium rolled sheet is a non-heat-treatable, unalloyed (commercially pure) aluminium grade with a minimum aluminium content of 99.5%. It belongs to the EN AW-1050A series and is typically supplied in H14 (half-hard, strain-hardened) temper.
Historically, 1050A was known as S1B under the former British Standard, with the half-hard temper designated H4, resulting in the classification S1B H4. Today, it is internationally recognised as EN AW-1050A H14 aluminium sheet, widely used where high strength is not critical, but excellent formability, corrosion resistance, and surface finish are required.
GNEE supplies 1050A aluminium sheets that fully comply with European, British, and international specifications.
Typical Uses of 1050A Aluminium Plate
1050A aluminium sheet is commonly selected for general engineering applications where premium mechanical properties are unnecessary. Typical commercial uses include:
General sheet metal fabrication
Light engineering components
Decorative and architectural panels
Anodised aluminium products
Industrial covers and housings
Key Benefits of 1050A Aluminium Sheet
| Feature | Description |
|---|---|
| Surface Quality | Smooth surface with excellent anodising performance |
| Weldability | Very good MIG and TIG welding characteristics |
| Formability | Highly suitable for cold forming operations |
| Cost Efficiency | Economical processing due to simple composition |
| Material Purity | 99.5% pure aluminium |
Chemical Composition of 1050A Aluminium Sheet
| Element | Typical Content (%) |
|---|---|
| Aluminium (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 |
| Other (each) | ≤ 0.03 |
Machining Performance of 1050A Aluminium Plate
Due to its high purity, 1050A aluminium plate is relatively soft and therefore offers only fair machinability. Applying a half-hard (H14) temper improves surface hardness slightly, but alloyed aluminium grades generally perform better in applications involving friction or abrasion.
1050A aluminium is not a free-cutting or free-chipping grade and is best suited for forming rather than precision machining.
Corrosion Resistance of 1050A Aluminium Sheet
1050A aluminium sheet provides excellent corrosion resistance, making it suitable for typical industrial and marine environments. The natural oxide layer of pure aluminium protects the surface effectively against atmospheric corrosion.
For environments requiring higher resistance to aggressive marine conditions, alloyed aluminium grades such as 5251 (NS4) may offer enhanced performance.
Surface Treatment Properties of 1050A Aluminium Plate
1050A aluminium sheet demonstrates excellent anodising behaviour, making it ideal for both:
Technical anodising applications
Decorative and aesthetic surface finishes
It is also well suited to:
Electrolytic brightening
Chemical brightening
This makes 1050A aluminium plate a popular choice for architectural, lighting, and decorative products.
Welding Characteristics of 1050A Aluminium Sheet
1050A aluminium can be easily welded using MIG or TIG welding methods. When welded correctly, the joint strength can reach up to approximately 65 MPa, depending on:
Welding technique
Filler material
Weld quality
Recommended Filler Metals
| Welding Situation | Recommended Filler |
|---|---|
| 1050A to 1050A structures | 1050A (S-Al99.5) |
| General aluminium welding | 4043A (S-AlSi5) |
Proper filler selection is essential to ensure weld integrity and corrosion resistance.
