6061 6063 Square Aluminum Alloy Profile with High Corrosion Resistance and

We supply high-quality 6061 / 6063 square aluminum alloy profiles and full-series custom aluminum extrusion profiles, manufactured by advanced hot extrusion process, precise mold forming and standardized heat treatment. With stable alloy composition, smooth surface, high dimensional accuracy and excellent mechanical performance, our extruded aluminum profiles cover regular square tubes, square bars and customized special-shaped extrusion profiles. Factory direct sales ensure competitive pricing, stable supply and reliable quality, widely used in industrial manufacturing, construction decoration, equipment frames, transportation and daily hardware fields.

6063 is the most widely used Al-Mg-Si architectural and decorative aluminum alloy. It features outstanding extrusion performance, smooth and delicate surface, excellent anodizing, spraying and powder coating effect. With moderate strength, good toughness and strong corrosion resistance, it is easy to process, cut, bend and assemble. Perfect for decorative structures, light-duty frames, architectural accessories and daily industrial parts.

6061 is a high-strength structural aluminum alloy with heat-treatable performance. After T6/T5 temper treatment, it owns higher tensile strength, better load-bearing capacity and structural stability. It has great machinability, weldability and pressure resistance, not easy to deform under long-term load. Ideal for heavy-duty equipment frames, mechanical structural parts, automation accessories and engineering support components that require high rigidity and durability.

• Premium Extrusion Craftsmanship - Adopt one-piece hot extrusion molding, uniform internal structure, dense texture, no sand holes, no cracks and no impurities. Straight overall shape, precise right-angle design for square profiles, flat and neat surface with no burrs.
• Excellent Corrosion & Oxidation Resistance - Natural anti-rust and anti-oxidation performance, effectively resisting atmospheric erosion, moisture, weak acid and alkali. Long service life for indoor and outdoor installation, reducing later maintenance cost.
• Strong Customization Ability - We customize all kinds of aluminum extrusion profiles: square, rectangular, round, flat, hexagonal and special-shaped profiles. Custom size, wall thickness, length, section structure and processing requirements are all available to meet personalized engineering and production needs.
• Rich Surface Treatment Options - Standard mill finish for industrial use; optional anodizing, sandblasting, polishing, powder coating, electrophoretic painting and anti-corrosion treatment to improve texture, decoration and wear resistance.
• Easy Processing & Assembly - Light weight with high strength, easy to cut, drill, tap, punch, bend and weld. Convenient for on-site assembly, splicing and deep processing, greatly improving production and installation efficiency.
• Eco-Friendly & Recyclable - Aluminum alloy material is non-toxic, pollution-free and 100% recyclable, meeting global environmental protection and low-carbon industrial standards.
