1050A Aluminium plate Overview
1050A aluminium is a non-heat-treatable, unalloyed (commercially pure) aluminium grade, typically supplied in rolled sheet form. It is widely used in general engineering applications where superior mechanical strength is not essential, but consistent quality, ease of fabrication, and surface performance are required.
Under earlier British Standards, 1050A was known as S1B, with the half-hard temper referred to as H4, giving the designation S1B H4. Internationally, this material is recognized as EN AW-1050A H14, indicating a 99.5% pure aluminium sheet that has been strain-hardened to the half-hard condition. GNEE supplies 1050A aluminium alloy sheets in compliance with global quality and specification requirements.
1050 Aluminum Sheet Benefits and Typical Applications
1050A aluminium is valued across multiple industries due to the following advantages:
- Smooth surface finish with excellent anodising performance
- Very good welding characteristics
- Excellent cold-forming capability
- Economical processing and fabrication
- High ductility and reflective appearance
Common commercial applications include architectural components, general fabrication, decorative panels, industrial housings, and reflective products.
1050 Aluminum Sheet Machining Characteristics
Because of its high purity, 1050A aluminum is relatively soft, resulting in only fair machinability. The H14 half-hard temper improves overall hardness, but alloyed aluminium grades are generally more suitable for applications involving friction or abrasion. This grade is not free-cutting and is more often shaped through forming rather than machining.
1050 Aluminum Sheet Resistance
1050A aluminium provides excellent resistance to corrosion, performing reliably in standard industrial environments as well as many marine conditions. While some alloyed grades-such as 5251 (NS4)-may offer enhanced corrosion performance in specific situations, 1050A remains a dependable and cost-effective solution for most uses.
1050 Aluminum Sheet Surface Treatment Capabilities
This alloy demonstrates very good anodizing properties, making it suitable for both technical and decorative finishes. It also responds well to electrolytic and chemical brightening, allowing for visually appealing and functional surface treatments.
1050 Aluminum Sheet Welding Performance
1050A aluminium can be easily welded using MIG and TIG processes. When properly welded, joint strength can reach up to approximately 65 MPa, depending on the welding technique and workmanship. Suitable filler materials include 1050A (S-Al99.5) or 4043A (S-AlSi5) when welding to 1050A structures.
Aluminium 1050 – Scope and Uses
Aluminium 1050 is a popular choice for general sheet metal work where moderate strength, high ductility, and corrosion resistance are required. It is particularly known for its highly reflective finish.
