6063 Extruded Aluminum Shapes

6063 Aluminum is noted for having the best all-around extruding properties. It is an aluminum alloy, with magnesium and silicon as the alloying elements. It has generally good mechanical properties.
6063 can be used for comparatively intricate sections. It is an excellent option for hollow extrusions and architectural applications. It takes a good surface finish, is corrosion resistant, and can be anodized. The strength of 6063, as extruded, is somewhat higher than that of 3003. It can be precipitation heat-treated to strengths just under 6061 alloy and it can be welded.  6063 is primarily used in extruded shapes for architecture, particularly window frames, door frames, roofs, and sign frames. It is typically produced with tight corners, and very smooth surfaces fit for anodizing.
