• T1 Hot working => Cooling => Natural Aging
  e.g. Extrusion. Cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition. Thus, lower cold working effect while applying sizing.

• T2 Hot working => Cooling => cold working => Natural Aging
  e.g. Extrusion. Applying cooling process after manufactured in high temperature. Then, increase the strength by the cold working process. Lastly, apply the natural age hardening process to stabilize.

• T3 Hot working => Cooling => Natural Aging
  e.g. Extrusion. Applying cooling process after manufactured in high temperature. Then, apply the natural age hardening process to stabilize without the cold working process. Thus, the effect of the cold working process will be weaker when applying sizing.

• T4 Solution Treatment => Natural Aging
  Without applying cold working process after utilized the solution treatment process. Then, applying the natural age hardening process to stabilize. Thus, the effect of the cold working process will be weaker when applying sizing.

• T5 Hot working => Artificial Aging
  e.g. Casting or extrusion. Applying cooling process after manufactured in high temperature. Then, apply the artificial age hardening process to stabilize without the cold working process. Thus, the effect of the cold working process will be weaker when applying sizing.

• T6 Solution Treatment => Artificial Aging
  Apply artificial age hardening process instead of the cold working process after the solution treatment process. Thus, there will be a weaker effect of the cold working process when applying sizing.

• T7 Solution Treatment => Stabilizing Treatment
  To gain the maximum strength of artificial age hardening by adjusting specific characteristics after applied the solution treatment process

• T8 Solution Treatment => cold working => Artificial Aging
  Apply cold working process and artificial age hardening process to increase the strength after utilized solution treatment.

• T9 Solution Treatment => Artificial Aging => Cold Working
  Apply cold working process and artificial age hardening process to increase the strength after utilized solution treatment.

• T10 Hot working => Cooling => Cold Working => Artificial Aging
  e.g. Extrusion. Applying cooling process after manufactured in high temperature to enhance the strength. Then, apply the artificial age hardening process to stabilize.
