The differences between 6061T6 aluminum alloy and 6061T5 aluminum alloy
- 2017-03-05 10:07 -
6061 aluminum sheet belongs to Al-Mg-Si alloy, and is the most commonly used products of the 6000 series aluminum sheet. The most commonly used states in the market are 6061T6, T5 and other states. So what is the difference between T6 and T5?

First of all, in the production process, 2000 series, 6000 series and 7000 series aluminum sheet can be quenched to improve the strength of aluminum sheet. This is the process that T5 and T6 need to go through. The difference is that 6061 T6 refers to the aluminum sheets after high temperature need instant cooling water, which can meet the requirements of the hardness of aluminum sheet. But T5 is the use of air cooling rapid cooling after high temperature, in order to achieve the required hardness. From the point of view of time, the time required of T6 water cooling for artificial aging is shorter, but the natural aging of T5 air conditioning needs 2-3 days. However, in the application, the hardness of T6 is higher than T5 and the price increases 800 yuan per ton.
In addition, the market is often used to add a stretching process of 6061T651. Because T651 is often used for bending and deep drawing by customer follow-up processing, in the production of extruded aluminum heating internal tensile energy must be fully released, if not released, the latter may be produced aluminum sheet bending, wave and other phenomena.
