Properties of 1235 aluminum foil
High purity, aluminum content ≥99.35%
1235 belongs to the 1xxx series aluminum alloy with high purity and very low impurity levels, giving it excellent chemical stability and oxidation resistance. It is ideal for applications requiring non-reactive and contamination-free materials, such as food, pharmaceutical, and electronic packaging.
Soft and highly ductile, ideal for deep processing
In the annealed condition (such as O temper), 1235 aluminum foil offers superior ductility and formability. It is easy to die-cut, emboss, laminate, and bond, making it suitable for aluminum-plastic films, capacitor foils, tobacco inner liners, and other high-adhesion composite materials.
Good electrical conductivity for electronics and battery use
The crystalline structure of high-purity aluminum gives 1235 foil excellent conductivity. It is widely used in lithium battery current collectors, pouch packaging, cable shielding foil, and EMI shielding applications.
Lightweight and flexible, with structural stability
Compared with higher-strength alloy foils, 1235 offers better flexibility and lightweight performance. It is especially suited for roll applications in automated packaging lines, laminated film rolls, and medical banding.
Cost-effective and energy-efficient
As a pure aluminum alloy, 1235 benefits from lower raw material and processing energy costs. With mature processing technology and no need for heat treatment, it offers better price competitiveness than 2xxx, 5xxx, or 8xxx series alloys.
Alternative to 1145 foil with stable market supply
1235 shares nearly identical chemical composition and physical properties with 1145, making it a suitable substitute in most applications. As demand for 1145 declines, 1235 has become the mainstream alternative with strong market prospects.

Why can 1235 aluminum foil replace 1145 aluminum foil?
Chemically very similar
1235 and 1145 both belong to the 1xxx series of pure aluminum, with aluminum content exceeding 99.3% and extremely low impurity levels. Their chemical compositions are nearly identical.
Comparable processing and performance
The two alloys show minimal differences in ductility, conductivity, and corrosion resistance. They are interchangeable in most manufacturing processes and end-use applications without significantly affecting product performance.
1235 aluminum foil offers better availability and cost
1235 foil has greater production capacity and more suppliers in the current market. In contrast, 1145 is becoming less common, with reduced output and higher prices. From a cost-performance and supply stability perspective, 1235 is a more advantageous choice. Contact for detail.
Industry-recognized substitute
In flexible packaging, capacitors, cable shielding, and pharmaceutical foil applications, 1235 has become the standard replacement for 1145—especially in cost-sensitive scenarios or where ultra-high purity is not critical.
