2. What Is 140μm 3003 H24 Tegita Aluminia Folio?

140μm 3003 H24 coated aluminum foil is a precision-rolled aluminum product manufactured from AA3003 aluminum alloy, processed into the H24 temper condition, and subsequently coated with functional or decorative coatings to improve surface performance.

Understanding the 140μm Thickness

Thickness plays a critical role in determining the mechanical behavior and application suitability of aluminum foil.

Thickness Conversion

Ĉe 140 mikronoj, the material is substantially thicker than conventional packaging foil, which typically ranges from 6–50 μm.

3003 Enkonduko de Aluminia Alojo

3003 aluminia folio apartenas al la Al-Mn (Aluminum-Manganese) alloy family and is one of the most widely used aluminum alloys globally.

The alloy contains approximately 1.0–1.5% manganese, which significantly increases strength compared with commercially pure aluminum.

Typical Chemical Composition

What H24 Temper Means

Temper designation is critical in determining aluminum performance.

Definition of H24

According to aluminum temper classifications:

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

En praktikaj terminoj, 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.

Coated Process of Aluminum Foil

6. Manufacturing Process of 140μm 3003 H24 Tegita Aluminia Folio

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.

Oleo restaĵo, oxide instability, polvo, or moisture can weaken coating adhesion.

6.4 Coating Application and Curing

The coating may be applied by roller coating, Lokado, or lamination-related processes.

After application, controlled drying and curing create the required adhesion, fleksebleco, kaj kemia rezisto.

6.5 Fendado, Ebenigo, 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 Kvalita Inspektado

Inspection usually covers thickness, larĝo, plateco, surfacaj difektoj, coating adhesion, Pinholes, mekanikaj propraĵoj, and packaging quality.
