Temperature is one of the most common methods to change the mechanical properties of some grades of aluminum. Therefore, it is extremely important to understand the tempering name and its meaning of aluminum, so that it will not lead to fracture and failure due to misunderstanding.
The tempering code of aluminum is a series of letters and numbers, which are used to indicate the type of tempering treatment experienced by aluminum alloys. There is a dash before the tempering code, which is placed after the aluminum alloy code (such as 6061-T6). Knowing what the tempering code of aluminum means is very important for choosing the right material. This is very important, because the chemical composition of one aluminum alloy and another aluminum alloy may be exactly the same, but if the tempering code of the two is different, the mechanical properties of the two alloys will be very different.
There are many different tempering names for various aluminum alloys, but some are more common than others, especially in some applications. The following are some of the most popular tempering names of aluminum alloys and their applications.
