Composition of alloy 1235 Aluminum：
The main components of 1235 aluminum foil are as follows.
- Aluminum: 99.35%
- Iron Silicon: 0.65%
- Vanadium: 0.05%
- Magnesium: 0.05%
- Copper: 0.05%
- Other elements: 0.03%
1235 aluminum foil is a pure aluminum foil alloy that is primarily composed of aluminum, with small amounts of other elements like iron, silicon, and manganese. It has a high aluminum content of 99.35%, which makes it highly ductile and malleable. This foil is typically produced by rolling the aluminum ingots through a series of rolling mills, which gradually reduce the thickness of the foil to the desired level.
1235 alloy aluminum can not only be processed into the form of aluminum foil, but also can be customized into 1235 aluminum sheet, 1235 aluminum plate, 1235 aluminum coil, 1235 aluminum tube, etc.

Applications of 1235 Aluminum Foil
1235 aluminum foil is widely used in various industries due to its unique properties. Here are some of its most common uses:
Embossed aluminum foil for wrapping chocolate
Food Packaging
One of the most common uses of 1235 aluminum foil is in the food packaging industry. It’s an ideal material for food packaging because it’s lightweight, flexible, and has excellent barrier properties. It can also be easily printed on, making it a popular choice for branded packaging(1235 O temper).
Household Use
1235 aluminum foil paper is commonly used in households for wrapping food, lining baking trays, and covering dishes. It is also used in the production of aluminum foil containers, which are widely used in the food industry for packaging and transporting food(1235 O temper).
Pharmaceutical packaging
1235 aluminum foil is commonly used for pharmaceutical packaging. Its high barrier properties make it an excellent choice for packaging materials that require protection from light, moisture, and air(1235 O and 1235 H18 temper).
Other Applications
1235 aluminum foil is also used in other applications, such as:
Insulation foil:
Aluminum foil is 88 percent reflective and is widely used for thermal insulation, heat exchanges, and cable liners. Foil-backed building insulation not only reflects heat but also provides a protective vapor barrier.
Electronic foil:
Foil in electrical capacitors provides compact storage for electric charges. If the foil surface is treated, the oxide coating works as an insulator.
Geochemical Sampling:
Aluminum foil is used by geochemists to protect rock samples. Foil provides a seal from organic solvents and does not taint the samples as they are transported from the field to the lab.
Art and Decoration foil:
Anodizing aluminum foil creates an oxide layer on the aluminum surface that can accept colored dyes or metallic salts. Through this technique, aluminum is used to create inexpensive, brightly colored foils.
Cigarette packaging
The aluminium foil for cigarette packaging has basically replaced asphalt moisture-proof paper because of its high softness, decoration and protection, It has become the leading packaging material for cigarette packaging.
1235 aluminum foil is a versatile material that is widely used in packaging, electrical, and other applications. Its unique properties make it an excellent choice for applications that require high barrier properties, thermal and electrical conductivity, and lightweight.
