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
У практичном смислу, 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.

Coated Process of Aluminum Foil
6. Manufacturing Process of 140μm 3003 H24 Coated Aluminum Foil
6.1 Alloy Casting and Rolling
Production begins with aluminum ingots and controlled alloying additions. Manganese gives 3003 its improved strength and corrosion resistance.
After casting and homogenization, the material passes through hot rolling and cold rolling to approach the target gauge.
6.2 Temper Control to H24
The mill controls cold reduction and annealing to achieve H24 temper.
This step matters because excessive hardness may reduce formability, while insufficient hardness may cause poor shape retention.
6.3 Surface Pretreatment
Before coating, the foil surface needs proper cleaning and pretreatment.
Остаци уља, oxide instability, прашина, or moisture can weaken coating adhesion.
6.4 Coating Application and Curing
The coating may be applied by roller coating, лакирање, or lamination-related processes.
After application, controlled drying and curing create the required adhesion, флексибилност, и хемијску отпорност.
6.5 Сечење, Нивелисање, and Rewinding
The coated foil is slit to the required width. Accurate slitting reduces burrs, edge cracks, and winding defects.
Stable tension control protects surface quality and prevents telescoping or coil deformation.
6.6 Контрола квалитета
Inspection usually covers thickness, ширина, спљоштеност, површински недостаци, coating adhesion, рох, механичка својства, and packaging quality.
