The 1050 aluminum alloy sheet is a commercially pure aluminum alloy containing at least 99.5% aluminum. It is known for its outstanding corrosion resistance, making it suitable for a wide range of atmospheric and chemical environments. This alloy also boasts excellent thermal and electrical conductivity, ideal for applications involving heat transfer and electrical components.
Thanks to its good formability and workability, the 1050 aluminum plate can be easily bent, drawn, or spun into complex shapes without cracking. Although it cannot be strengthened by heat treatment, its strength can be enhanced through cold working processes, available in various tempers such as O, H12, H14, H16, and H18.
Lightweight by nature, the 1050 aluminum plate reduces overall structural weight, which is advantageous in many industrial and architectural applications. It also offers good surface finish compatibility, allowing for anodizing, polishing, coating, and other surface treatments to meet aesthetic and functional requirements.
While the 1050 aluminum plate has relatively low strength compared to other aluminum alloys, it compensates with excellent reflectivity, especially when polished or anodized, making it highly valuable in lighting and decorative uses. Additionally, it is fully recyclable, supporting environmentally friendly practices and cost-effective reuse.
1050 aluminum plate, with its high aluminum content (≥99.5%), excellent corrosion resistance, good workability, and high ductility, is commonly used in applications where high strength is not the primary requirement. Typical uses include:
