Aluminium alloy 6063 t6

Aluminium alloy 6063 t6 is the most common alloy metal material used for aluminum extrusion. It refers to the state of artificial aging after solution heat treatment. This base material is suitable for processing requirements that do not undergo cold processing after cooling in the high-temperature molding process. The processing formability and anodizing effect of 6063 alloy are better.


The common tempers of alloy 6063 base material are O, T4, T6, T651. The aluminum alloy of O temper has low hardness and is easy to cut; while the strength of T temper is relatively high. The general thickness range is 0.3-600 mm, the width range is 500-2650mm, and the length range is 500-16000mm.

Aluminium alloy 6063 t6 mechanical properties

The mechanical properties of aluminium alloy largely depend on the tempering or heat treatment of the material. Aluminum alloy 6063 t6 does not undergo cold working after solution heat treatment, but heats the alloy to an appropriate temperature and keeps it for a certain period of time to enhance the performance of the alloy and increase the hardness. But in the comparison of 6061 vs 6063 aluminum, the latter is slightly better in terms of plasticity.


6063-T6 physical properties

T6 temper 6063 grade has an ultimate tensile strength of at least 190MPa (28,000psi) and a yield strength of at least 160MPa (23,000psi). At a thinner thickness, such as 3.15 mm (0.124 inch) or less, its elongation is 8% or higher; at a thicker thickness, it can reach an elongation of 10%.

Can aluminium alloy 6063 be welded?

6063 is weldable and uses tungsten inert gas welding. Generally, 6063 of O temper is more common but t6 is also possible. After welding, there will be a certain loss of performance strength near the weld. At this time, the material can be heat treated again to restore the higher performance of the entire part.

aluminium alloy 6063 t6 scope of application

Aluminum alloy 6063 t6 has excellent properties such as good strength, anti-corrosion and wear-resistance, and high temperature resistance. It is mostly used in construction and industrial fields. In automobile manufacturing, it can be used as a raw material for the processing and manufacturing of car body parts, and can also be used as a processing material for tank car bodies; in the construction field, it can be used as decorative panels, anti-corrosion panels, and deep processing.
