The difference between the annealed, H18 and H24 states lies in the strength and ductility of the material. The annealed or H111 state is the state with the lowest mechanical strength that the material can have. The H24 state is an intermediate state that balances the strength and transformability of the material and, finally, the H18 state has greater mechanical strength but performs worse in terms of transformability.
