1235 aluminum alloy is a high-purity grade in the 1000 series, with a minimum aluminum content of 99.35%. Designated as EN AW-1235 (Al99.35) under the European standard, it is valued for its excellent flexibility, superior barrier performance against light and gases, and high thermal and electrical conductivity. As a non-heat-treatable alloy, 1235 gains its strength through cold working and is typically supplied in the O (Annealed) and H18 (Full Hard) tempers.
The high purity of 1235 aluminum ensures stable chemical properties and consistent performance in demanding barrier applications. It is the industrial standard for cigarette packaging foil, food packaging, battery foils, and cable shielding, where total protection against moisture, light, odors, and bacteria is essential. The alloy is also easily laminated with paper or plastic films, making it a versatile choice for multi-layer packaging constructions.
Linsy supplies 1235 aluminum in multiple product forms, with the primary form being foil. Custom dimensions and tempers are available on request. Each form is covered by MTC documentation.
1235 aluminum foil is the most commonly supplied form of this alloy. It is widely used for cigarette lining foil, flexible food packaging, aseptic liquid containers, battery current collectors, and cable wrapping foil. Typical foil thickness ranges from 0.006 mm to 0.2 mm, with widths customized to customer requirements. Foil can be supplied in O temper for maximum formability or H18 temper for higher rigidity.

| Other elements, each | ≤0.03 |
The mechanical properties of 1235 aluminum vary depending on the temper. The table below shows typical mechanical property values for the commonly supplied tempers. O temper provides maximum ductility and formability, while H18 offers higher strength and rigidity.
| Temperamento | Resistência à tração, máxima (MPa) | Resistência à tração, rendimento (MPa) | Alongamento (%) |
|---|---|---|---|
| 1235-O | 75–105 | 35–55 | ≥3 |
| 1235-H18 | Higher than O temper | Higher than O temper | Lower than O temper |
Note: The values listed for O temper are sourced from the original product data. H18 temper typically exhibits higher tensile strength and lower elongation. Specific H18 mechanical property values can be confirmed with our technical team upon request.
Choosing the right temper is key to matching 1235 aluminum to your application. As a non-heat-treatable alloy, 1235 develops its properties through cold working. The following guide summarizes the commonly supplied tempers and their typical use cases.
| Temperamento | Condition | Benefício Principal | Aplicações típicas |
|---|---|---|---|
| O | Annealed (soft) | Maximum ductility, flexibility, and formability; ideal for foil converting and lamination | Cigarette foil, food packaging foil, battery foil, cable wrapping, adhesive tapes |
| H18 | Full hard (strain-hardened) | Higher strength and rigidity for structural or semi-rigid applications | Rigid foil containers, heat insulation panels, semi-rigid packaging |
With a minimum aluminum content of 99.35%, 1235 alloy offers stable chemical properties and consistent performance. The high purity minimizes impurity-related variations, making it reliable for applications requiring strict quality control such as food contact and battery components.
1235 aluminum provides a total barrier against light, moisture, odors, gases, and bacteria. This makes it the material of choice for packaging applications where product protection and shelf life extension are critical. The barrier performance is effective even at very thin foil gauges.
In the O temper, 1235 aluminum exhibits excellent formability and can be easily laminated with paper, plastic films, or other substrates. This versatility supports multi-layer packaging constructions and composite materials used across the packaging and insulation industries.
The high purity of 1235 aluminum gives it excellent electrical and thermal conductivity. This makes it suitable for electrical shielding applications, capacitor foils, and battery current collectors where efficient current transfer is required.
1235 aluminum is used across multiple industries where high purity, barrier performance, and formability are the primary requirements. Below are representative applications by sector.
