6061-T6 Precision Aluminum Square Tube 30×40×2.2mm | Industrial-Grade Structural Profile
Certified to GB/T 3191 standards, this 30×40×2.2mm aluminum profile achieves ≥180MPa tensile strength with 14% elongation, combining lightweight efficiency (2.73g/cm³) and exceptional load-bearing capacity. The T6 heat-treated 6061 alloy features Mg₂Si reinforcement phases (Mg 1.0%, Si 0.6%) that enhance stress corrosion resistance by 30% versus standard alloys. Precision thermal extrusion ensures ±0.2mm dimensional accuracy and ≤5% wall thickness variation, ideal for high-tolerance mechanical frameworks.
Advanced Manufacturing & Protection
With 10-15 Webster hardness and ≥10μm anodized coatings (48hr salt spray compliant), the profile withstands harsh outdoor environments. Choose between brushed or anodized finishes (silver/black) for enhanced aesthetics and protection. Our AI-controlled extrusion process delivers Ra≤0.8μm inner surface smoothness, eliminating burrs for precision assembly with M6/M8 fasteners.
