6061-T6 Aluminum Square Tube 35×35×1.6mm | Structural Precision Redefined
Certified to ASTM B221/EN 573-3 standards, this 35×35×1.6mm aluminum profile delivers 310MPa tensile strength at 2.7g/cm³ density - achieving 60% weight reduction versus steel with unmatched corrosion resistance. Precision-engineered with 6061-T6 alloy's optimized Mg (0.8-1.2%)/Si (0.4-0.8%) chemistry, the Mg₂Si precipitates ensure thermal stability across -50°C to 150°C environments. The 1.6mm±0.1mm uniform walls maintain <0.12mm/m straightness, ideal for aerospace tooling and semiconductor handling systems.
