6061 High-Strength Aluminum Profile 40×40×2.4mm | Precision Engineered Structural Solutions
Certified to ASTM B221 standards, this 40×40×2.4mm aluminum square tube redefines structural efficiency with 10-15 Webster hardness - perfectly balancing machinability and load-bearing capacity. Precision-extruded from 6061 alloy (Mg 0.8-1.2%, Si 0.4-0.8%), the profile achieves 2.7g/cm³ density (60% lighter than steel) while maintaining ≤0.1mm/m straightness tolerance. Ideal for robotics and automated production lines, its 2.4mm uniform walls withstand repeated assembly cycles without deformation.
