5083 h22 aluminum plate sheet

5083-H22 aluminum is 5083 aluminum in the H22 condition, with a strength approximately one-quarter of the strength between annealed (O) and full hard (H28) states.

5083-H22 aluminum alloy is a material with specific mechanical properties. The H22 condition means the aluminum has undergone strain hardening followed by partial annealing.

Material Condition: In the H22 condition, 5083 aluminum alloy has been strain-hardened to increase its strength. This strain hardening is achieved by applying mechanical stress during processing to enhance the material's hardness and strength.
Partial Annealing: After strain hardening, the aluminum undergoes partial annealing. This process involves heating the aluminum to a certain temperature, holding it for a period, and then slowly cooling it to reduce internal stress and improve plasticity (though it does not fully return to the initial state).
Strength Level: The strength of 5083 aluminum in the H22 condition is between that of the fully annealed (O) and full hard (H28) states.

5083-H22 aluminum plate is a high-strength, corrosion-resistant marine-grade aluminum alloy (5083) produced in the H22 temper. This means it has undergone strain hardening and partial annealing, achieving a good balance between strength and formability. It features excellent corrosion resistance (especially to seawater), high strength, good weldability, and suitability for low-temperature environments. Therefore, it is widely used in shipbuilding, vehicle bodies (trucks and rail vehicles), armor plate, and cryogenic applications, where it is resistant to embrittlement at low temperatures.
