5052 aluminum alloy belongs to Al-Mg alloy, which has a wide range of applications, especially the construction industry cannot do without this alloy. 5052 aluminum has good corrosion resistance, excellent weldability, good cold workability and medium strength. The temper of 5052 aluminum alloy includes O temper, H32, H34, H36, H38 and other states.

5052-o vs 5052-h32

What are the difference of 5052-o vs 5052-h32? The O temper represents the 5052 aluminum sheet with the lowest strength after complete annealing, while H32 represents the 5052 aluminum sheet whose mechanical properties are stable after work hardening and then low temperature heat treatment. In short, the strength and mechanical properties of the 5052 H32 aluminum alloy are better than those in the O annealed temper. H32 and O tempers of 5052 aluminum sheet are the heat treatment states of aluminum sheets, and the mechanical properties corresponding to different heat treatment states are clearly specified in the national standard. H32 aluminum plate has higher tensile strength and is suitable for scenarios that require higher strength of aluminum plate, such as chassis shell, aluminum alloy luggage, etc. The O temper aluminum plate has good elongation performance and can be used in scenes such as stretching and spinning.


5052 aluminum alloy is a high-hardness aluminum alloy, which is 100% higher than the hardness of 1060 aluminum plate, reaching between 210-230. Moreover, the alloy includes a variety of different states, and the hardness of each state is very different. For example, 5052-o vs 5052-h32, the hardness of 5052 O state aluminum sheet is about 46HB; the hardness of 5052 H32 aluminum sheet is about 60HB; the hardness of 5052-H34 aluminum plate is about 68HB; the hardness of 5052-H36 aluminum plate is about 73HB.
