Note: In the Brush name:
- "A" represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
- "H" stands for cold processing state (hard);
- "T" means that the material has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).
