Basic knowledge of T4/T5/T6 aluminum profiles
We often see the material column marked with 6063-T5/T6, or 6061-T4, etc. These materials are sometimes used to produce parts in bobcat zero turn parts diagram, gravely pro turn 460 parts diagram, gravely zero-turn parts diagram and kubota zero turn parts diagram. The 6063 or 6061 in this mark is the grade of aluminum profile, and T4/T5/T6 is the state of aluminum profile, so what is the difference between them?
- The T4 state is: solution treatment + natural aging, that is, the aluminum profile is cooled after being extruded from the extruder, but it is not placed in the aging furnace for aging. The aluminum profile in the unaged state has a relatively low hardness and good deformation ability, which is suitable for the parts in the bcat zero turn parts diagram, gravely pro turn 460 parts diagram, gravely zero-turn parts diagram and kubota zero turn parts diagram to be bent and deformed later.
- The T5 state is: solution treatment + incomplete artificial aging, that is, after extrusion, it is air-cooled and quenched, and then transferred to an aging furnace and kept at about 200 degrees for 2-3 hours. The state of the aluminum material after it is released. Aluminum in this state has relatively high hardness and has a certain deformability.
- The T6 state is: solid solution treatment + complete artificial aging, that is, it is water-cooled and quenched after extrusion. The artificial aging after quenching is higher than the T5 temperature and the holding time is longer, thereby achieving a higher hardness state. Its adaptability Suitable for occasions where the material hardness is required to be relatively high.
