6082 Aluminum Square Tube
6082 aluminum square tubes have a cross-section of 10×10~300×300mm, wall thickness of 1.2~8mm, and length of 6~12m (custom lengths available), primarily in T6 temper. Our Chinese factory provides processing services: cutting, drilling, bending, welding, CNC machining, anodizing, and painting. We also support non-standard customization and export packaging.
6082 aluminum square tubes are square-section tubing made of 6-series Al-Mg-Si-Mn heat-treatable strengthened aluminum alloy. They are high-strength structural aluminum profiles, second only to 6005A in strength within the 6000 series, and boast three core advantages: high strength, excellent weldability, and resistance to seawater corrosion.

Processing Points
1. Heat Treatment: Aluminum square tube manufacturers recommend using the T6 temper (solution treatment + artificial aging) to obtain optimal mechanical properties.
2. Welding Method: TIG welding is preferred to maximize joint strength.
3. Surface Treatment: Oxidation and spraying are both acceptable; anodizing is recommended to improve corrosion resistance and appearance.
