What Is a 1050A Aluminum Sheet?
1050A aluminum sheet is a non-heat-treatable, unalloyed aluminum grade belonging to the 1xxx series. It contains 99.5% pure aluminum, offering excellent corrosion resistance, high ductility, and good surface quality.
Historically, 1050A was known as S1B under the former British Standard, with the half-hard temper designated S1B H4. Today, it is internationally recognized as EN AW 1050A H14, which refers to a strain-hardened, half-hard aluminum sheet.
GNEE supplies 1050A aluminum sheets suitable for a wide range of general engineering and industrial applications where high mechanical strength is not critical.
Key Benefits of 1050A Aluminium Sheet
Good Surface Finish & Anodising Quality of 1050A Aluminium
1050A aluminum sheet features a smooth, clean surface that delivers excellent anodizing performance, making it suitable for both technical and decorative applications. It also performs well in electrolytic and chemical brightening processes, producing an attractive and durable finish.
Cold Forming Capability of 1050A Aluminium Sheet
Thanks to its high purity, 1050A aluminum sheet is highly ductile and can be easily processed by cold forming methods, including bending, rolling, and pressing. This makes it ideal for general sheet metal fabrication.
Cost-Effective Processing of 1050A Aluminium Sheet
As an unalloyed aluminum grade, 1050A aluminum sheet can be processed economically, providing a cost-efficient solution for large-volume applications without compromising corrosion resistance or surface quality.
Machining Characteristics of 1050A Aluminium Sheet
Due to its purity, 1050A aluminum is relatively soft and offers fair machinability. The half-hard (H14) temper improves hardness to some extent, but alloyed aluminum grades are better suited for applications involving high friction or abrasion.
1050A is not a free-cutting aluminum grade, and machining operations should be performed with appropriate tooling and parameters.
Corrosion Resistance of 1050A Aluminium Sheet
1050A aluminum sheet provides excellent corrosion resistance, allowing it to perform reliably in industrial and mild marine environments. While certain alloyed grades such as 5251 (NS4) may offer enhanced performance in specific conditions, 1050A remains a dependable choice for general corrosion-resistant applications.
Welding Performance of 1050A Aluminium Sheet
1050A aluminum sheet offers very good weldability and can be easily welded using MIG or TIG processes. When welded correctly, joint strength can reach up to approximately 65 MPa, depending on welding technique and quality.
Recommended filler metals include:
1050A (S-Al99.5)
4043A (S-AlSi5)
