2. What Is 140μm 3003 Foglio di alluminio rivestito H24?

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

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

3003 Introduzione alla lega di alluminio

3003 foglio di alluminio appartiene a 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

In termini pratici, 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.

Coating System: Why It Matters

The coating transforms the aluminum substrate into an application-specific material.

Depending on the end use, the coating may provide corrosion resistance, food-contact protection, heat-sealing performance, decorazione, isolamento, or bonding compatibility.

3. Technical Specifications of 140μm 3003 Foglio di alluminio rivestito H24

For critical applications such as food-contact lids, pharmaceutical-related sealing foil, or HVAC fin stock, coating specifications should include adhesion, resistenza alla corrosione, sealing performance, and compliance declarations.

4. Proprietà meccaniche e fisiche

The performance of 140μm 3003 H24 coated aluminum foil is primarily determined by the mechanical characteristics of the 3003 alloy and the strengthening effect of the H24 temper.

• Buona formabilità: 3003 alloy and H24 temper support punching, shallow drawing, flessione, and lid forming.
• Better stiffness: 140μm thickness improves shape retention compared with thin foil.
• Resistenza alla corrosione: The Al-Mn substrate and coating layer help protect against moisture, food ingredients, and mild industrial exposure.
• Coating functionality: The coating can add heat sealing, anti-corrosion protection, stampabile, or bonding performance.
• Stabilità dimensionale: H24 temper helps reduce unwanted deformation during slitting, rewinding, e formando.
• Sustainability value: Aluminum can be recycled, and recycled aluminum can save about 95% of the energy required for primary aluminum production.

Coated Process of Aluminum Foil

6. Manufacturing Process of 140μm 3003 Foglio di alluminio rivestito H24

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.

Residui di olio, oxide instability, polvere, or moisture can weaken coating adhesion.

6.4 Coating Application and Curing

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

After application, controlled drying and curing create the required adhesion, flessibilità, e resistenza chimica.

6.5 Taglio, Livellamento, 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 Ispezione di qualità

Inspection usually covers thickness, larghezza, planarità, difetti superficiali, coating adhesion, Pinchi, proprietà meccaniche, and packaging quality.
