6061 High-Strength Aluminum Profile 40×40×2.2mm | Industrial-Grade Precision Extrusions
Certified to ASTM B221 standards, this 40×40×2.2mm aluminum square tube delivers superior strength-to-weight ratios with 10-15 Webster hardness. The precision-extruded 6061 alloy features optimized Mg (0.8-1.2%)/Si (0.4-0.8%) chemistry, achieving 2.7g/cm³ density (60% lighter than steel) while maintaining ≤0.15mm/m straightness tolerance. Ideal for semiconductor equipment frameworks and EV battery enclosures, its 2.2mm uniform walls withstand 300N/mm² compressive loads with minimal deformation.
Technical Superiority
① Material Science
Mg₂Si phase formation enhances thermal stability (-30°C to 150°C)
Cr (0.04-0.35%) improves stress corrosion resistance by 30% vs standard alloys
Ultra-low impurities (Fe≤0.7%, Cu≤0.4%) ensure ASTM E1251-compliant grain structure
② Surface Engineering
