6063 aluminium alloy
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 the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames. Applications requiring higher strength typically use 6061 or 6082 instead.
Chemical composition
The alloy composition of 6063 is:Mechanical properties
The mechanical properties of 6063 depend greatly on the temper, or heat treatment, of the material.6063-O
Un-heat-treated 6063 has maximum tensile strength no more than, and no specified maximum yield strength. The material has elongation of 18%.6063-T1
T1 temper 6063 has an ultimate tensile strength of at least in thicknesses up to, and from thick, and yield strength of at least in thickness up to and from thick. It has elongation of 12%.6063-T5
T5 temper 6063 has an ultimate tensile strength of at least in thicknesses up to, and from thick, and yield strength of at least up to and from. It has elongation of 8%.6063-T6
T6 temper 6063 has an ultimate tensile strength of at least and yield strength of at least. In thicknesses of or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%.Other tempers
6063 is also produced in tempers T52, T53, T54, T55, and T832, with various improved desiredproperties.
