    Note: In the Brush name:
    "A" stands for solid solution annealing (annealed, the alloy is in the softest state, and it is easy to be stamped and formed, and needs to be processed in the next cold process or directly strengthened during the expiration period);
    "H" stands for cold working state(hard);
    "T" indicates that the material has been subjected to aging hardening by standard heat treatment (heat treatment indicates that the aging strengthening heat treatment has been performed).
