FAQ
1. What is the difference between 6063 and 6061 aluminum alloy?
6063 is optimized for extrusion, surface finish, and corrosion resistance, commonly used for architectural profiles.
6061 has higher strength and is used for structural and load-bearing applications.
2. What tempers are available for 6063?
Commonly T5 (artificially aged after extrusion) and T6 (solution heat-treated and artificially aged), offering different strength and hardness.
3. Can 6063 be anodized or painted?
Yes. Excellent surface finish quality allows anodizing, powder coating, and painting, widely used for decorative and architectural purposes.
4. Is 6063 aluminum suitable for outdoor and marine environments?
Yes. It offers high corrosion resistance in outdoor, humid, and mild marine environments, especially when anodized or coated.
5. Can 6063 be welded or machined?
Yes. Compatible with TIG/MIG welding, machining, cutting, bending, and extrusion.
Welding may slightly reduce strength; post-weld treatment is recommended for critical applications.
6. Can 6063 aluminum be customized?
Yes. Available in sheets, plates, bars, tubes, and custom extrusion profiles, with custom sizes, wall thicknesses, and surface treatments.
7. What certifications are provided?
Mill Test Certificates (EN 10204 3.1)
Chemical and mechanical property report
Optional third-party inspection (SGS, BV, Intertek)
