Differences between 5052 aluminum plate h24 and h32

5052 aluminum plate

European aluminum sheet supplier introduces the difference between 5052 aluminum plate H24 and H32

Different annealing conditions of 5052 aluminum plate , their alloy composition is the same，and the difference between H32 and H24 stems from the heat treatment process.

The first digit after HXX state H represents the basic handler that gets the state.

1.H1 — pure work hardening treatment state.

Suitable for obtaining the desired strength by work hardening without additional heat treatment.

2.H2 – work hardening and incomplete annealing.

It is suitable for products whose working hardening degree exceeds the requirements of finished products and whose strength is reduced to the specified index after incomplete annealing. For alloys softened by natural aging at room temperature, There are same minimum ultimate tensile strength between H2 and the corresponding H3 , for other alloys, the same is true for H2 and its corresponding H1, but the elongation is slightly higher than H1.

3.H3—The state of work hardening and stabilization treatment.

It is suitable for products which are heat treated after work hardening or whose mechanical properties are stabilized due to heat during processing. The H3 state is only suitable for alloys that gradually age soften at room temperature (unless stabilized).

4.H4—The state of work hardening and painting treatment.

Applicable to incompletely annealed product that produced by process hardening and coating. paint treatment after work hardening.

5.The second digit after H indicates the work hardening degree of the product.

The number 8 represents the hard degree. Generally, the sum of the minimum tensile strength of O state and the strength difference specified in table 2 is adopted to determine the m=nimum tensile strength value of HX8. For the states between O(annealing) and HX8 states,Numbers from 1 to 7 should be added after HX code to represent them respectively. After HX, Numbers 9 should be added to represent the super-hard state with higher work-hardening degree than HX8.And various HXX subdivision status codes are added to clearly indicate the corresponding degree of work hardening.
