Weldability & Brazability
Workability
Machinability
The strength of 6063 tuong thuat truc tiep bong da alloy is considered medium, slightly lower than higher-strength alloys like 6061. Although it is not suitable for heavy-duty structures, it is sufficient for general architectural profiles and medium to light industrial applications. It provides basic structural support while maintaining good formability.
6063 has excellent corrosion resistance, especially after anodizing, which forms a dense protective layer that effectively resists oxidation and atmospheric corrosion. It is particularly suitable for outdoor use, such as doors, windows, curtain walls, and railings, which are exposed to natural environments for long periods.
6063 tuong thuat truc tiep bong da alloy is suitable for various common welding methods, making it easy to process. For welding, 5183 or 4043 alloy welding wires are typically used. If conductivity is more important, 4043 is recommended; if stronger welds are desired, 5346 welding wire can be used. However, due to its lower conductivity, the weld size may need to be increased to compensate.
6063 offers excellent extrudability and can be processed into various complex profiles, making it ideal for customized needs in the industrial and construction fields. It also has good bending, forming, and stamping capabilities, making it suitable for various manufacturing processes.
Although it can be machined by turning, drilling, and other methods, 6063's machinability is not as good as certain higher hardness alloys, such as 6061 or 2024. When machining, it is necessary to choose the appropriate tools and cutting parameters to achieve better surface quality.

Why is 6063 tuong thuat truc tiep bong da alloy suitable for anodizing?
6063 belongs to the Al-Mg-Si alloy series, with moderate silicon (Si) and magnesium (Mg) content, which prevents the formation of rough, spotted, or dull surfaces that some high-silicon alloys may produce. This makes 6063 form a uniform and delicate oxide film after anodizing.
With tuong thuat truc tiep bong da content above 97.5% and very low impurity levels such as iron and copper, 6063 avoids color changes or instability in the oxide film due to impurity reactions during anodizing, ensuring better film formation and more stable color.
6063 alloy was originally designed for use in architectural windows, doors, curtain walls, and other decorative applications. Therefore, its formulation balances strength with appearance quality after anodizing, providing excellent results after anodizing, coloring, electrophoresis, powder coating, and other surface treatments.
After anodizing, the surface of 6063 tuong thuat truc tiep bong da forms a dense tuong thuat truc tiep bong da oxide layer, offering excellent weather resistance and corrosion resistance, making it ideal for outdoor environments (such as curtain walls, balconies, and window and door profiles).
