3A21 Aluminum Bar
3A21 Aluminum Alloy is a commercially pure aluminum, containing approximately 99.0% aluminum. While it cannot be strengthened by heat treatment, it offers excellent ductility, formability, and weldability, making it easy to work with for various applications. In addition to its good corrosion resistance, the alloy also responds well to anodizing, which not only further enhances its resistance to corrosion but also gives it a smooth and aesthetically pleasing surface.
Although it has low strength, 3A21 aluminum is ideal for applications that require materials with high formability and the ability to withstand environmental conditions. The alloy’s corrosion resistance ensures long-term durability in various industries.
Typical uses for 3A21 aluminum include:
-
Construction: panels, roofing materials, and other structural components
-
Automotive and transportation: lightweight parts, trim, and body components
-
Electrical and electronics: connectors, fittings, and other components requiring good conductivity
-
Household items: cookware, appliances, and decorative items
With its excellent workability, corrosion resistance, and attractive surface finish, 3A21 aluminum remains a popular choice for cost-effective manufacturing where high strength is not the primary concern but durability and aesthetic appeal are important.
