Aluminum alloys in different temper have different properties and processing process routes. It is necessary to prepare a suitable processing process according to the temper of the aluminum alloy.
Introduction to the basic Temper of aluminum
| Code | Temper | Application |
| F | Fabricated | Applied to products without special requirements for work hardening and heat treatment conditions during the forming process, the mechanical properties of products in this state are not specified |
| O | Annealed | Applied to processed products that have undergone complete annealing to obtain the lowest strength. |
| H | Strain Hardened | Applied to products that increase strength through work hardening, the product can undergo (or may not undergo) additional heat treatment to reduce strength after work hardening. The H code must be followed by two or three Arabic numerals |
| W | Solut heat trated | Applied to alloys that undergo solution heat treatment and undergo natural aging at room temperature, this state code only indicates that the product is in the natural aging stage |
| T | Heat treatment | Applied to products that have reached a stable state through (or without) work hardening after heat treatment |
Common Temper Detail of aluminum alloys
Aluminum alloys are more suitable for improving strength through strain hardened. The common degrees and temper of hardening are as follows
| Temper | Hardening degree |
| H12 | Work hardening to 25% hardness |
| H14 | Work hardening to 50% hardness |
| H16 | Work hardening to 75% hardness |
| H18 | Work hardening to 100% hardness strain hardening to 100% hardness (fully hardened state) |
| H22 | Partial annealing to 25% hardness after strain hardening |
| H24 | Partial annealing to 50% hardness after strain hardening |
| H26 | Partial annealing to 75% hardness after strain hardening |
| H28 | Partial annealing to 100% hardness after strain hardening |
