Aluminum 6063
Aluminum 6063 is a heat-treatable aluminum alloy commonly referred to as an architectural alloy due to its excellent surface finish, corrosion resistance, and suitability for complex extruded shapes. It’s widely used in applications where appearance, dimensional consistency, and moderate strength are required.
Compared to higher-strength alloys such as Aluminum 6061, Aluminum 6063 offers lower mechanical strength but superior extrudability and finish quality, making it ideal for decorative, structural, and architectural components. It responds well to anodizing and other surface treatments, which further enhances its corrosion resistance and appearance.
Aluminum 6063 is commonly supplied in extrusion form, including custom profiles, tubing, and shapes. It’s frequently specified for architectural framing, window and door systems, railings, trim, and other applications where tight tolerances and smooth surfaces are important.
Tech Steel & Materials supplies Aluminum 6063 extrusions and shapes with full material traceability and certifications, along with value-added services such as cutting, machining support, and specialized packaging.
FAQ
What is Aluminum 6063 used for?
Aluminum 6063 is commonly used for architectural and decorative applications, including window and door frames, railings, trim, and structural framing where a smooth surface finish and corrosion resistance are important.
What is the difference between Aluminum 6063 and Aluminum 6061?
Aluminum 6063 offers better surface finish and extrudability, while Aluminum 6061 provides higher mechanical strength and better machinability. As a result, 6063 is typically chosen for architectural extrusions, while 6061 is preferred for structural and machined components.
Is Aluminum 6063 bendable?
Yes, Aluminum 6063 has good formability, particularly in softer tempers, making it suitable for bending and forming operations commonly required in architectural and extrusion-based applications.
Is Aluminum 6063 weldable?
Yes, Aluminum 6063 is generally considered weldable using common aluminum welding methods, though mechanical properties in the weld zone may be reduced depending on temper and post-weld treatment.
