6061 Precision Aluminum Profile 40×40×2.0mm | Industrial-Strength Structural Solution
Engineered for demanding applications, this 40×40×2.0mm aluminum square tube combines 6061 alloy's superior strength (10-15 Webster hardness) with precision extrusion technology. Certified to ASTM B221 standards, the profile achieves 2.7g/cm³ density (60% lighter than steel) while maintaining optimal Mg (0.8-1.2%)/Si (0.4-0.8%) chemistry for enhanced corrosion resistance. The 2.0mm uniform walls ensure <0.15mm/m straightness tolerance, ideal for CNC machine bases and automated production line frameworks.
Technical Excellence
① Material Science
Controlled Cr (0.04-0.35%) content improves stress corrosion resistance by 25%
Ultra-low Fe (≤0.7%) ensures ASTM E407-compliant microstructure homogeneity
