Common Aluminium Foil Thicknesses and Product Types
Aluminium foil is available in different thicknesses for packaging, insulation, electrical, and household uses.
The correct thickness depends on the barrier requirements, forming method, mechanical strength, and whether the foil will be laminated or coated.
The ranges below are examples of common product categories, not a guarantee that every alloy is available in every size.
Thin Aluminium Foil for Flexible Packaging
Thin foil has used where low weight and barrier performance are important. It has combined with paper, plastic film, or other materials to make a flexible packaging structure.
| Product type | Example thickness | Possible alloys | Typical use |
|---|---|---|---|
| Extra-thin packaging foil | 0.006–0.009 mm | 8011, other specified grades | Flexible packaging laminates |
| Thin packaging foil | 0.010–0.015 mm | 8011, 1050, 1100 | Food and household packaging |
| Standard flexible packaging foil | 0.016–0.025 mm | 8011, 1050, 1100 | Laminated packaging |
| Heavy-duty household foil | 0.020–0.030 mm | 8011, 1100, other suitable grades | Food preparation and wrapping |
Very thin foil requires careful control of pinholes, surface cleanliness, and thickness tolerance. Buyers should also confirm whether the foil is supplied as bare material or as part of a finished laminate.
Medium-Thickness Aluminium Foil for Industrial Use
Medium-thickness foil offers a balance between flexibility and handling strength. It can be used for insulation facings, technical laminates, and some formed products.
| Product type | Example thickness | Possible alloys | Typical use |
|---|---|---|---|
| Insulation facing foil | 0.025–0.050 mm | 1050, 1060, 1100 | Building and HVAC insulation |
| Industrial laminated foil | 0.030–0.080 mm | 1050, 1100, 8011 | Protective and technical laminates |
| Electrical-use foil | 0.020–0.100 mm | 1060 or specified grade | Electrical components, subject to design requirements |
| General-purpose industrial foil | 0.050–0.150 mm | 1050, 1100, 8011 | Industrial wrapping and fabrication |
Electrical foil must meet the customer’s requirements for conductivity, surface condition, and thickness. Do not select an alloy by name alone when the product is part of a critical electrical design.
Thicker Foil and Thin Aluminium Strip
Some suppliers distinguish thicker foil from thin aluminium strip based on product thickness and the relevant industry specification. These materials have supplied in coils for slitting, stamping, or further processing.
| Product type | Example thickness | Possible alloys | Typical use |
|---|---|---|---|
| Heavy aluminium foil | 0.080–0.200 mm | 1050, 1100, 8011 | Industrial wrapping and formed parts |
| Thin aluminium strip | 0.150–0.300 mm | 1050, 1060, 1100 | Electrical and industrial components |
| Precision aluminium strip | 0.200–0.500 mm | Grade selected by design | Stamping and precision fabrication |
Confirm the product classification, tolerance, and standard with the manufacturer. A material described as aluminium strip may be subject to different dimensional and mechanical requirements from thin foil.
Aluminium Foil Tempers: O, H14, H18 and Other Conditions
Temper describes the condition of the aluminium after processing. It affects softness, strength, elongation, and forming performance.
O Temper Aluminium Foil
O temper is annealed and generally soft. It is suitable for products that need high flexibility or significant forming.
Common uses include:
- Household foil
- Flexible packaging
- Deep-forming applications where the specification permits
- Insulation facings
- Laminated foil products
O temper can be a good starting point when bending or forming is more important than stiffness. However, the required forming depth and final shape should be confirmed before production.
H14 and H24 Aluminium Foil
H14 and H24 are strain-hardened tempers with different processing histories. Their exact properties depend on the alloy and applicable standard.
| Temper | General condition | Selection consideration |
|---|---|---|
| O | Annealed | High flexibility and formability |
| H12 | Strain-hardened, lower strength level | Moderate stiffness with useful formability |
| H14 | Strain-hardened | General-purpose semi-hard condition |
| H18 | Fully strain-hardened condition in the relevant temper system | Higher strength, lower formability than soft temper |
| H22 | Strain-hardened and partially annealed | Balance of strength and forming ability |
| H24 | Strain-hardened and partially annealed | Useful balance for selected formed products |
Not every alloy and thickness is available in every temper. Some foil products use specialized temper designations. Buyers should request the exact designation and mechanical properties rather than relying only on a general label such as soft or hard foil.
Aluminium Foil Applications by Industry
The same alloy may serve different markets when its thickness, temper, coating, and processing method change. The following examples help buyers connect material specifications with the finished product.
Food Packaging and Household Products
Food packaging needs suitable barrier performance, clean surfaces, and reliable converting behavior. Aluminium foil has used alone or combined with other materials.

Pharmaceutical Packaging
Pharmaceutical packaging must protect products from moisture, light, and other environmental factors. The correct structure depends on the medicine and packaging design.
Typical applications include:
- Blister packaging
- Cold-form blister structures, where the specified material is suitable
- Strip packs
- Medicine sachet laminates
- Pharmaceutical lidding foil
8011 has commonly used in pharmaceutical foil products. However, not every 8011 foil is suitable for every pharmaceutical structure. Buyers should specify whether they need bare foil, printed foil, lacquered foil, or foil for lamination.
Electrical and Electronic Applications
Electrical products may require aluminium foil with controlled conductivity, surface quality, and thickness.
Potential uses include:
- Electrical shielding components
- Selected capacitor-related materials
- Cable and wire shielding structures
- Electrical insulation laminates
- Heat management components
1060 and other high-purity grades may be considered when conductivity is important. The correct material depends on the electrical design and manufacturing process. For specialized capacitor foil, buyers should state the exact application because surface treatment and processing requirements can be highly specific.
Building and HVAC Insulation
Aluminium foil has used as a facing or reflective layer in insulation systems. It may be laminated to foam, mineral wool facings, paper, or other substrates.
Typical applications include:
- Duct insulation
- Pipe insulation
- Roof and wall insulation facings
- Reflective insulation laminates
- Industrial thermal insulation
- HVAC protective layers
1050, 1060, 1100, and other suitable grades have considered depending on the thickness and laminate structure. The final system’s fire performance, vapor control, and installation requirements must be assessed separately from the foil alloy.
Industrial and Manufacturing Uses
Industrial buyers often need foil or thin strip that has slit, stamped, coated, or laminated.
Possible applications include:
- Heat transfer components
- Protective wrapping
- Technical laminates
- Stamped foil parts
- Industrial insulation
- Decorative and surface-treated products
For these uses, dimensional consistency and edge quality can be as important as the alloy. A sample trial can help confirm whether the material runs well on the customer’s production line.
Bare Aluminium Foil vs Coated and Laminated Foil
Aluminium foil can be supplied in different surface conditions. The right finish depends on the final product and whether the foil needs to bond with another material.
| Product type | Description | Common applications |
|---|---|---|
| Bare aluminium foil | No added coating specified | General foil processing and laminating |
| Lacquered foil | Surface has a specified lacquer coating | Packaging and selected lidding applications |
| Printed foil | Printed surface for product information or branding | Food and pharmaceutical packaging |
| Paper-laminated foil | Aluminium foil bonded to paper | Packaging and insulation facings |
| Plastic-film-laminated foil | Foil bonded to a polymer film | Flexible packaging |
| Embossed foil | Surface has a patterned texture | Decorative or specialized products |
A coating or laminate can change sealing performance, surface protection, appearance, and recyclability. Buyers should state the coating type, coating side, color, and performance requirements in the purchase specification.
How to Choose the Right Aluminium Foil Alloy
Selecting a grade becomes easier when the application and processing method are clear. A lower material price does not always mean a lower production cost.
The wrong alloy or temper can cause more scrap, slower production, or poor forming results.
Choose by Final Application
Start with the finished product rather than the alloy name.
| Main requirement | Grades to evaluate | What to confirm |
|---|---|---|
| General-purpose foil | 1050, 1100 | Formability, surface and thickness |
| High-purity electrical use | 1060 or another specified grade | Conductivity, temper and applicable standard |
| Pharmaceutical packaging | 8011 or specified packaging grade | Barrier structure, pinholes, coating and sealing |
| Household foil | 8011, 1100 or suitable alternative | Flexibility, tear behavior and thickness |
| Insulation facing | 1050, 1060, 1100 or other suitable grade | Lamination, surface and thermal system requirements |
| Formed industrial parts | Alloy selected for the forming process | Elongation, strength and cracking risk |
These are starting points only. The final choice has checked against the customer’s technical specification and end-use requirements.
Choose by Thickness and Temper
Thickness and temper work together. Thin foil is lightweight and flexible, while thicker material is generally easier to handle. A hard temper can improve stiffness but may reduce formability.
Before ordering, confirm:
- Nominal thickness and tolerance
- Coil width and width tolerance
- Required temper
- Minimum elongation or strength, if applicable
- Surface condition and permitted defects
- Whether the foil will be bent, stamped, laminated, or deep-formed
For high-speed converting lines, stable dimensions and consistent mechanical properties can help reduce downtime.
Choose by Surface Quality
Surface quality matters for both appearance and production. Packaging foil may need clean surfaces for coating or lamination. Electrical products may have additional requirements for cleanliness and surface condition.
Ask the supplier about:
- Pinholes and inspection criteria
- Oil residue and surface cleanliness
- Scratches, dents, and edge damage
- Surface brightness or finish
- Coating adhesion, where applicable
- Slitting burrs and edge condition
For very thin foil, the acceptable pinhole level has agreed before production. Different end uses have different quality requirements.
Common Aluminium Foil Specifications
The table below shows an example inquiry format for bulk buyers. Values are indicative and should be confirmed with the supplier.
| Specification | Example options |
