H state is a common state of aluminum finished products, on behalf of the aluminum plate into the work hardening treatment to improve the strength of aluminum. Aluminum has five basic states (F, O, H, W, T), H state is the most contact with us, the most state of a breakdown of the state, with the specifications, the same grade aluminum, subdivision state, performance Will also be very different.2024 aluminum plate
The H state is expressed as follows:
H followed by 2-3 digits, said H-state subdivision, 2-digit state of the most common.
The first digit indicates the processing status of the aluminum plate:
H1: Work-hardened state, indicating that the aluminum plate without heat treatment, only by work hardening is to obtain the required strength.1060 aluminum plate
H2: work hardening and incomplete annealing state, indicating that the aluminum plate after processing hardening, strength exceeds the requirements, after incomplete annealing, so that the strength of aluminum plate reduced to the standard strength.
H3: work hardening and stabilization of the state, said the aluminum plate after heat treatment or processing in the heat, the mechanical properties to achieve stability. H3 is only suitable for natural aging aluminum sheets at room temperature.
H4: Work hardening and painting treatment state, said the aluminum plate in the work hardening, the paint treatment led to incomplete annealing of the aluminum plate.
The second digit indicates the strength of the aluminum plate and the degree of work hardening:
