6063T5

6063T5 refers to an aluminum alloy product that combines the 6063 alloy with a T5 temper designation. The 6063 alloy is a member of the 6xxx series, composed primarily of aluminum with magnesium and silicon as the major alloying elements. This composition provides a favorable balance of strength, formability, and corrosion resistance, making it well suited to extrusion and architectural applications.

The T5 temper indicates the material has been solution heat treated and artificially aged to a stable condition. This aging process increases strength compared with natural aging, while preserving good ductility and a smooth surface finish. Compared with other tempers in the same alloy, 6063-T5 offers moderate strength with good workability and corrosion resistance typical of the 6xxx series.

Common applications for 6063-T5 include extruded architectural and structural profiles such as window and door frames, curtain wall components, railings, and decorative trims. It is also used in automotive and electrical enclosure parts where a combination of good surface finish, formability, and resistance to weathering is valuable. The alloy is widely available in bars, rods, tubes, and extruded shapes.

In processing, extrusion is a primary manufacturing method, followed by aging to achieve the T5 temper. Machining characteristics are generally favorable, though post-extrusion aging can influence hardness and dimensional stability. Weldability is acceptable with standard techniques; heat-affected zones can alter temper, so appropriate welding practices or post-weld aging may be considered depending on the application. Overall, 6063-T5 is chosen for applications demanding a balance of appearance, corrosion resistance, and moderate strength.
