6063
6063 is a wrought aluminum alloy in the 6xxx series, formed primarily from aluminum with magnesium and silicon as the main alloying elements. The combination of Mg and Si gives good extrusion characteristics and enables precipitation hardening to increase strength. 6063 is widely used for extruded profiles in architectural and construction applications where a smooth surface finish and good corrosion resistance are important.
Typical composition ranges include magnesium about 0.45–0.9% and silicon about 0.2–0.6%, with small amounts of iron,
6063 is heat-treatable and commonly supplied in temper designations such as T5 and T6, which reflect artificial
Applications for 6063 include architectural extrusions, window and door frames, curtain-wall components, piping and tubing, and
