01 Aluminum and magnesium alloys are also strengthened by heat treatment.
In aluminum alloys, the Al-Cu-Si AC2A, Al-Si-Mg AC4A, and Al-Si-Cu ADC12 alloys are subjected to Solution treatment → aging treatment (T6 treatment) can be applied to increase strength. Heat treatment temperatures vary slightly depending on the alloy type, but solution treatment temperatures range from 500 to 530°C and aging treatment temperatures range from 150 to 250°C. Magnesium alloys include Mg-Al, Mg-Al-Zn, and Mg-Zn alloys, and their strength can be increased by T6 treatment. Solution treatment temperatures range from 400~530℃, and aging treatment temperatures range from 150~250℃. The quality symbols for these materials are specified in JIS.
| basic symbol | subdivision sign | meaning |
| F: AS MANUFACTURED | ||
| O: ANNEALED (SOFTEST STATE) | ||
| H: WORK HARDENING | H1 | Work hardening only |
| H2 | Moderate softening heat treatment after work hardening | |
| H3 | Stabilization treatment after work hardening | |
| H4 | Coating after processing effect | |
| W: SOLUTION ANNEALING (APPLICABLE ONLY TO ALLOYS THAT AGE SPONTANEOUSLY AT ROOM TEMPERATURE AFTER SOLUTION ANNEALING) | ||
| T: HEAT TREATMENT | T1 | Natural aging after cooling from high temperature processing |
| T2 | After cooling from high-temperature processing, cold working is performed, and then natural aging is performed. | |
| T3 | Solution treatment is followed by cold working and then natural aging. | |
| T4 | Natural aging after solution treatment | |
| T5 | Artificial age hardening treatment after cooling from high temperature processing | |
| T6 | Solution treatment followed by artificial age hardening treatment | |
| T7 | Solution treatment followed by stabilization treatment | |
| T8 | After solution treatment, cold working is performed, followed by artificial age hardening treatment. | |
| T9 | Solution treatment is followed by artificial age hardening, and then cold working. | |
| T10 | After high-temperature processing and cooling, cold working is performed, followed by artificial age-hardening treatment. |
