AA 6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. The standard controlling its composition is maintained by The Aluminum Association. It has generally good mechanical properties and is heat treatable and weldable. It is similar to the British aluminium alloy HE9.

6063 is mostly used in extruded shapes for architecture, particularly window frames, door frames, roofs, and sign frames. It is typically produced with very smooth surfaces fit for anodizing.

The mechanical properties of 6063 depend greatly on the temper, or heat treatment, of the material

6063-T5

T5 temper 6063 has an ultimate tensile strength of at least 22,000 psi (152 MPa) in thicknesses up to 0.5-inch (13 mm), and 21,000 psi (145 MPa) from 0.5 to 1.0-inch (25 mm) thick, and yield strength of at least 16,000 psi (110 MPa) up to 0.5-inch (13 mm) and 15,000 psi (103 MPa) (from 0.5 to 1.0-inch (25 mm). It has elongation of 8%.

6063-T6

T6 temper 6063 has an ultimate tensile strength of at least 30,000 psi (196 MPa) and yield strength of at least 25,000 psi (165 MPa). In thicknesses of 0.124-inch (3.1 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%.

Welding

6063 is highly weldable, using tungsten inert gas welding. Typically, after welding, the properties near the weld are those of 6063-0, a loss of strength of up to 30%. The material can be re-heat-treated to restore a higher temper for the whole piece.
