6063 T5 T6 aluminum extrusion

As an aluminum profile manufacturer, we all know that both architectural aluminum profiles and industrial aluminum profiles are mainly made of 6063 grades, that is, aluminum-magnesium-silicon alloys. 6063 T5 T6 aluminum extrusion has excellent formability, strong corrosion resistance, and certain weldability, and the hardness after aging can basically meet the requirements for use. So very popular.

People who may not know much about aluminum profiles do not know that aluminum profiles of the same brand also have different states. There are three common states of 6063 aluminum profiles: T5\T6.

T is the meaning of treatment in English, and the following 5 and 6 represent the heat treatment method. In technical terms, T5 state is solution treatment + incomplete artificial aging; T6 state is solution treatment + artificial complete aging. In fact, this is not entirely correct for 6063 grade aluminum profiles.

6063 T5 aluminum extrusion is one of the most commonly produced ones. It is air-cooled and quenched after extrusion, and then transferred to an aging furnace to keep the temperature at about 200 degrees for 2-3 hours. The state of the aluminum profile can reach T5 after being released. The aluminum profile in this state has relatively high hardness and certain deformability. Therefore, most architectural aluminum profiles and industrial aluminum profiles are in this state.

The 6063 T6 aluminum extrusion state is quenched by water cooling, and the artificial aging temperature after quenching will be higher and the holding time will be longer to achieve a higher hardness state. In fact, our company can also meet the hardness requirements of T6 by using strong air cooling and quenching. 6063-T6 is suitable for occasions with high requirements on material hardness.
