Both 1100-H14 aluminum and 1100-H24 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing. There are 31 material properties with values for both materials.
Among the tempers from O to H32, the most common temper of the 1100 aluminum sheet is h14, we called it aluminum sheet 1100 h14. The H temper is hard representation, H is followed by 2-3 digits, indicating the subdivision temper of the H.
Take 1100 aluminium sheet as the example, the first digit indicates the processing status of the 1100 aluminum sheet:
H1: Work hardened temper, indicating that the aluminum sheet 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 1100 aluminum sheet has been work hardened and the strength exceeds the specified requirements. After incomplete annealing, the strength of the aluminum sheet is reduced to the standard strength.
H3: The state of work hardening and stabilization treatment indicates that the aluminum sheet is subjected to heat treatment during heat treatment or processing, and the mechanical properties are stabilized. H3 is only suitable for aluminum sheets that are naturally aged at room temperature.
H4: Work hardening and painting treatment state, indicating that the aluminum sheet is subjected to painting treatment after work hardening, resulting in incompletely annealed.
The second digit indicates the strength of the aluminum sheet and the degree of work hardening. Generally, the degree of hardening is divided into 8 grades, 1 is the lowest, 8 is the highest, and 9 is the superhard state which is higher than the Hx8 work hardening degree. E.g:The aluminum sheet 1100 H14 indicates that the aluminum sheet is only subjected to work hardening and not been subjected to heat treatment and has the moderate strength.
