What Are Popular Uses of Aluminum Foil Alloy 1235

Aluminum foil alloy 1235, with its high purity (typically aluminum content exceeding 99.35%), excellent ductility, superior processing properties, and manageable costs, has defied the traditional perception that aluminum foil is "only used for packaging." Its applications have expanded from everyday life to industrial production, demonstrating a wide range of popular applications.

1. Packaging

In food packaging, 1235 aluminum foil, with its excellent barrier properties (effectively blocking oxygen, moisture, and light) and high-temperature resistance, perfectly addresses the dual needs of food preservation and heating. For example, the commonly seen aluminum foil linings of ready-to-eat lunch boxes, made with 1235 aluminum foil, not only withstand the high temperatures of microwaves and ovens (maximum temperatures exceeding 200°C), but also lock in moisture and flavor, preventing nutrient loss during heating.

Furthermore, it is widely used in individual packaging for chocolate and candy. Its thin and tough properties prevent damage while enhancing the product's texture with its metallic sheen, making it a visually appealing choice for high-end snack packaging. In the field of daily chemical packaging, 1235 aluminum foil is a "sealing expert."

Many skincare products (such as creams and serums) and cosmetics (such as eyeshadow palettes and lipstick inserts) use 1235 aluminum foil as a sealing layer. Its excellent sealing properties prevent oxidation and deterioration of the product through contact with air, while also blocking bacterial contamination and extending its shelf life.

2. Electronics

In lithium battery manufacturing, 1235 aluminum foil is a key current collector material. It can be processed into ultra-thin foil, just a few microns thick, and evenly coated on the surface of the lithium battery's positive electrode, collecting current and conducting electrons.

Due to its high purity and low impurity content, 1235 aluminum foil effectively reduces internal resistance losses in batteries, improving charge and discharge efficiency and cycle life. It is currently widely used in new energy vehicle batteries, mobile phone batteries, and other fields, becoming a key contributor to the rapid development of the new energy industry.

In addition, 1235 aluminum foil also plays a vital role in shielding electronic components. It can be processed into shielding sheets with specific shapes through calendering and cutting, and then wrapped around precision components such as circuit boards and chips. Aluminum's metallic conductivity blocks electromagnetic interference (EMI), preventing malfunctions caused by signal interference between electronic devices. This application is particularly common in high-end electronic products such as laptops and smart wearables.

3. In the construction and industrial sectors

In building insulation, 1235 aluminum foil jumbo roll is often combined with materials such as thermal insulation cotton and foam board to create "aluminum foil insulation material." Its metal surface reflects over 80% of infrared rays, effectively preventing heat from transmitting through walls and pipes.

This provides significant insulation in both winter and summer, and is currently widely used for insulating building exterior walls and roofs, as well as wrapping and insulating central air conditioning and heating ducts, helping buildings achieve energy conservation and emission reduction goals.

In industrial processing, 1235 aluminum foil, due to its excellent plasticity, has become a mold-aiding material. For example, in the production of metal castings, laminating 1235 aluminum foil to the mold surface can not only reduce the adhesion between the casting and the mold, but also ensure the smoothness of the casting surface and reduce subsequent processing costs.

In addition, it is also used as a "protective coating substrate" on the metal surface. Through surface coating treatment, it forms a corrosion-resistant and high-temperature resistant composite coating, which is used in chemical equipment, medical equipment and other fields.
