What H24 Temper Means
Temper designation is critical in determining aluminum performance.
Definition of H24
According to aluminum temper classifications:
- Х = Strain Hardened
- 2 = Quarter Hard
- 4 = Partially Annealed after Strain Hardening
Практикалык жактан, 3003-H24 provides a balance between strength and ductility.
It is stronger and stiffer than annealed 3003-O, but more formable than harder tempers such as H26 or H18.
