Typical Chemical Composition

What H24 Temper Means

Temper designation is critical in determining aluminum performance.

Definition of H24

According to aluminum temper classifications:

• এইচ = Strain Hardened
• 2 = Quarter Hard
• 4 = Partially Annealed after Strain Hardening

ব্যবহারিক দিক থেকে, 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.

H24 is often selected when the foil must hold shape, resist deformation, and still tolerate forming or punching without cracking.
