| Surface Finish | Coating Process |
As industries increasingly demand lightweight, corrosion-resistant, and highly formable materials, 140μm 3003 H24 coated aluminum foil has become an important engineering material in packaging, construction, insulation, HVAC systems, household appliances, and industrial manufacturing.
Combining the excellent corrosion resistance of 3003 aluminum alloy, the balanced mechanical properties of the H24 temper, and the enhanced protection provided by specialized coating systems, this material offers an optimal combination of durability, processability, and cost efficiency.
At a thickness of 140 microns (0.14 mm), the foil occupies a unique position between traditional aluminum foil and thin-gauge aluminum sheet.
It provides greater structural stability than ultra-thin foils while maintaining the flexibility and lightweight advantages associated with aluminum materials.
The combination of alloy composition, temper condition, and coating technology makes 140μm 3003 H24 coated aluminum foil an ideal material for applications requiring a balance between strength, corrosion resistance, formability, and aesthetic appearance.
140μm 3003 H24 Coated Aluminum Foil
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.
Thickness plays a critical role in determining the mechanical behavior and application suitability of aluminum foil.
Thickness Conversion
| Unit | Value |
|---|---|
| Micrometers | 140 μm |
| Millimeters | 0.14 mm |
| Inches | 0.0055 in |
At 140 microns, the material is substantially thicker than conventional packaging foil, which typically ranges from 6–50 μm.
3003 aluminum foil belongs to the 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
| Element | Content (%) |
|---|---|
| Aluminum (Al) | Balance |
| Manganese (Mn) | 1.0–1.5 |
| Copper (Cu) | 0.05–0.20 |
| Silicon (Si) | ≤0.60 |
| Iron (Fe) | ≤0.70 |
| Zinc (Zn) | ≤0.10 |
Temper designation is critical in determining aluminum performance.
Definition of H24
According to aluminum temper classifications:
In practical terms, 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.
| Temper | Strength Level | Formability | Typical Use |
|---|---|---|---|
| 3003-O | Low | Excellent | Deep drawing, soft forming |
| 3003-H14 | Medium | Good | General sheet and foil forming |
| 3003-H22 | Medium-low | Very good | Moderate forming applications |
| 3003-H24 | Medium-high | Good | Coated foil, lids, semi-rigid formed parts |
| 3003-H26 | Higher | Moderate | Stiffer parts with limited forming |
| 3003-H18 | High | Limited | High stiffness, minimal forming |
H24 is often selected when the foil must hold shape, resist deformation, and still tolerate forming or punching without cracking.

140μm 3003 H24 coated aluminum foil performs well when the application needs both strength and processability.
Main performance advantages include:
Coated Process of Aluminum Foil
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.
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.
Before coating, the foil surface needs proper cleaning and pretreatment.
Oil residue, oxide instability, dust, or moisture can weaken coating adhesion.
The coating may be applied by roller coating, lacquering, or lamination-related processes.
After application, controlled drying and curing create the required adhesion, flexibility, and chemical resistance.
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.
Inspection usually covers thickness, width, flatness, surface defects, coating adhesion, pinholes, mechanical properties, and packaging quality.
140μm 3003 H24 Coated Aluminum Foil for Construction
The versatility of 140μm 3003 H24 coated aluminum foil stems from its balanced mechanical properties, excellent corrosion resistance, attractive surface finish, and ease of fabrication.
