Aluminum alloy No. 1050, H stands for work hardening state, Hxx state description: The first digit 1 stands for simple work hardening state, suitable for the required strength without additional heat treatment, only work hardening. The second digit represents the hardened state, the number 0 represents the annealing, ie the soft state, 8 represents the hard state, 9 represents the super-hard state, and the numbers 1 to 7 represent the state between 0 (annealed) and 8 (hard state).
Corresponding to H14 representative: without heat treatment, only work hardening, so that the tensile strength of the material reaches the intermediate value of 0 (annealing) and 8 (hard state), that is, the average.
The meaning of each digit in 1050-H24 is as follows:
