Distinguish Between 5083H111 And 5083H112
5083H111 and 5083H112 themselves belong to the same 5083 aluminum alloy, and the two are essentially the same, and there is no difference in chemical composition.
The attached tables of 5083H111 and 5083H112 (namely H111 and H112) indicate a work hardening state of the product, which means that it is suitable for products whose strength is increased by work hardening. The product can pass through ( It is also possible not to undergo additional heat treatment to reduce the strength. Here, we will introduce the subdivision status of H.
The first digit after H represents the basic processing procedure to obtain this state, as shown below: H1-simple work hardening processing state. It is suitable for the state where the required strength can be obtained only after work hardening without additional heat treatment. H2—Work hardened and incompletely annealed state. It is suitable for products whose work hardening degree exceeds the specified requirements of the finished product and is incompletely annealed to reduce the strength to the specified index. For alloys that are naturally aged and softened at room temperature, H2 and the corresponding H3 have the same minimum ultimate tensile strength value; for other alloys, H2 and the corresponding H1 have the same minimum ultimate tensile strength value, but the elongation is slightly higher than H1 . H3—The state of work hardening and stabilization. It is suitable for products whose mechanical properties are stabilized by heat treatment after work hardening or due to heat during processing. The H3 state is only applicable to alloys that are gradually aging and softened at room temperature (unless they are stabilized).
H4—The state of work hardening and painting. It is suitable for products that have been incompletely annealed after work hardening.
The second digit after H indicates the degree of work hardening of the product. The number 8 represents the hard state. Usually the minimum tensile strength of O state and the sum of the strength difference specified in Table 2 are used to specify the minimum tensile strength of HX8. For the state between O (annealed) and HX8 state, a number from 1 to 7 should be added after the HX code to indicate that the number 9 is added after HX to indicate a super-hard state with a greater degree of work hardening than HX8
The code of HXXX state is as follows: a) H111: It is suitable for products that have undergone a proper amount of work hardening after final annealing, but the degree of work hardening is not as good as that of H11 state. b) H112: Suitable for hot-processed products. The mechanical properties of products in this state have specified requirements. c) H116: Suitable for products made of 5XXX series alloys with magnesium content ≥4.0%. These products have specified mechanical properties and anti-flaking corrosion performance requirements. d) The status code of the checkered plate.
