2A12 Aluminum Tube is a high-strength, heat-treatable aluminum alloy tube widely used in demanding structural and industrial applications. As a member of the 2000 series aerospace-grade aluminum alloys, the 2A12 tube combines excellent tensile strength, fatigue resistance, and machinability with tailored temper options (like T4, T6, and T351) for performance-driven projects. Its high copper content enhances mechanical properties after heat treatment, making it ideal for lightweight yet high-load components in aerospace, automotive, marine, industrial machinery, and construction equipment. Although its corrosion resistance is moderate, surface treatments such as anodizing or painting are commonly applied to extend service life.
