W raporcie z testu lub opisie materiału znajduje się AA1100-H24, więc co oznacza ten model? Nie martw się, dzisiaj pokażę Wam kilka modeli w okleinie aluminiowej. Po zrozumieniu, Wierzę, że przy następnym zakupie okleiny aluminiowej awansujesz na profesjonalistę.
Liczby w naszych wspólnych opisach materiałów, takich jak 1100, 1050, 1060, 3003, I 5005 are the aluminum content of the aluminum plate, of which the 1 series are industrial pure aluminum with an aluminum content of more than 90%. Na przykład, 1050 represents an aluminum content of 99.5%. 1060 reprezentuje 99.6% zawartość aluminium. Numer 3003 represents AL-Mn alloy, which is the most widely used anti-rust aluminum. Wytrzymałość tego stopu nie jest wysoka (slightly higher than that of industrial pure aluminum) i nie mogą być wzmocnione przez obróbkę cieplną, so cold working method is used to improve its mechanical properties. wydajność.
The letter H after the number is a common state of the finished aluminum sheet, which means that the aluminum sheet has undergone work hardening treatment to increase its strength. The H state is a common state of the finished aluminum sheet, which means that the aluminum sheet has undergone work hardening treatment to improve the strength. Spośród 5 basic states of aluminum plates (F, O, H, W, T), the H state is the state we most often come into contact with and has the most subdivision states. Aluminum plates of the same specification and brand have different subdivision states. , the performance will vary greatly. H state means adding 2-3 digits after H to indicate the subdivision state of H state, and the state of 2 digits is the most common.
The first digit indicates the processing state of the aluminum plate:
H1: Work hardening state, indicating that the aluminum plate has not been heat treated, and the required strength is obtained only by work hardening.
H2: Work hardening and incomplete annealing state, indicating that the aluminum plate has been work hardened, and the strength exceeds the specified requirements. After incomplete annealing, the strength of the aluminum plate is reduced to the standard strength.
H3: The state of work hardening and stabilization, which means that the mechanical properties of the aluminum plate are stable after heat treatment or heating during processing. H3 is only suitable for naturally aged aluminum sheets at room temperature.
H4: Work hardening and painting treatment state, indicating that the aluminum plate is not completely annealed after painting treatment after work hardening.
The second digit indicates the strength of the aluminum plate and the degree of work hardening:
Ogólnie, the degree of hardening is divided into 8 klas, 1 jest najniższa, 8 jest najwyższy, I 9 reprezentuje stan supertwardy o wyższym stopniu umocnienia przez zgniot niż Hx8. Na przykład, the H18 state means that the aluminum plate is only work-hardened and heat-treated, and the strength reaches the maximum. H24 state, indicating that the aluminum plate has been partially annealed after work hardening, and the strength is medium. The H32 state means that the aluminum plate is annealed at a low temperature after work hardening, and the state is stable, but the strength is lower than that of the H24 aluminum plate.
