Detailed classification and meaning of aluminum plate status
The basic state of aluminum plate is divided into 5 types, namely F, O, H, T, W. These 5 states represent the 5 processing processes and stages of aluminum plate. The performance and price of aluminum plate in different states will be very different. . When you buy aluminum sheets, you only know the brand name but not the status. Not only may you buy the wrong aluminum sheet, but you will also be deceived by the bad business.
So, what are the meanings of the five states? F state F state is also called free processing state. The mechanical and chemical properties of F state aluminum sheet are not clearly specified. Customers who purchase F state aluminum sheet generally have special requirements for aluminum sheet performance. After purchasing, they will perform the required work hardening and heat treatment. Obtain the required mechanical and chemical properties.
O state The O state is also called the fully annealed state. The O state has no subdivision state. It refers to the aluminum sheet product with the lowest strength after only complete annealing. H state The H state is also called the work hardening state, which represents the aluminum plate that has been hardened to increase the strength.
H state has many subdivision states, such as H18 state, the following 1 and 8, the first digit represents the processing technology: 1 is work hardening, 2 is incomplete annealing after processing, 3 is low temperature annealing after processing; the second digit Representative hardness: 1-8, 1 is the lowest, 8 is the highest.
T state T state refers to the heat treatment state of the aluminum plate, which means that the aluminum plate is stable after work hardening. The T state has a subdivision state, which represents different processing techniques, and the state goes from T0 to T10. In the T state, Tx51 represents the elimination of internal stress, such as the T6 state. After the internal stress is eliminated, it is expressed as T651.
W state W state refers to the state of solution heat treatment, W state is an unstable state, which means that the aluminum plate is in natural aging at room temperature after solution treatment, and W state only means that the aluminum plate is in the natural aging stage...
