6061 5083 3003 2024 7075 T6 Aluminum Alloy Square Tubes ASTM Anti Corrosion Durable

Products Description

Core General Performance Attributes

• Standard Compliance Fully produced and inspected per ASTM industry standard, stable chemical composition, low impurity content, uniform internal grain structure, consistent batch quality.
• Outstanding Anti-Corrosion & Weather Resistance Natural oxidation resistance plus optimized alloy formula, excellent resistance to seawater, salt spray, humid atmosphere, ultraviolet radiation and weak acid-base environment. Not easy to rust, oxidize or discolor under long-term indoor and outdoor exposure.
• High Durability & Structural Stability T6 heat treatment process eliminates internal stress, greatly improves overall toughness and fatigue resistance. Resist bending, deformation, impact and pressure, maintain stable structure for long-term service.
• Lightweight & High Strength Low density compared with steel, light weight for easy transportation and installation; meanwhile equipped with high tensile strength and yield strength, realizing light weight + high rigidity structural advantage.
• Precision Dimensional Accuracy Strict tolerance control on outer diameter, inner diameter, wall thickness, side length and straightness. High roundness for round tubes, high right-angle verticality for square tubes; no distortion, no ellipticity, perfect for precision assembly and matching.
• Superior Surface Quality Smooth inner and outer wall, no burrs, no scratches, no pits, no oxidation spots. Available in mill finish, anodized, polished and customized surface treatment, good decoration and wear resistance.
• Excellent Machinability & Processability Easy to cut, drill, bend, weld, punch, tap and CNC deep processing. Clean cutting section without burrs, no cracking or deformation after secondary forming, suitable for OEM custom fabrication.
