Aluminum 6063
Aluminum 6063 – Architectural Extrusion Alloy with Premium Surface Finish
Aluminum 6063 is the definitive architectural aluminum extrusion alloy, offering superior surface finish quality, excellent extrudability, and good corrosion resistance. While slightly lower in strength than 6061, its ability to achieve tight dimensional tolerances and accept anodizing makes it indispensable for architectural and decorative extrusions.
