so What is Aluminum foil grade 1235?

1235 Alloy Aluminum Foil is an aluminum alloy material commonly used in the packaging industry. It is as high as 99.35% pure, has good flexibility and ductility, and also has good electrical and thermal conductivity.

The surface is coated or painted to increase its resistance to corrosion and abrasion.

1235 Alloy Aluminum Foil is widely used in food packaging, pharmaceutical packaging, electrical and electronic product packaging and other fields.

1235-0 aluminum foil

1235-0 aluminum foil is a soft aluminum foil. The surface of aluminum foil after rolling is very smooth without any deformation and stretching, so it is called “0” state.

1235-0 aluminum foil can also be used as heat insulation material, because its surface is very smooth, which can effectively reflect heat radiation and reduce energy loss.

Alloy composition of aluminum 1235

The main component of 1235 alloy aluminum foil is aluminum, with a purity of more than 99.35%. The content of the remaining components is very low and will not have a significant impact on the performance of the aluminum foil.

Mechanical properties of 1235 alloy aluminum

1235 aluminum foil performs well in terms of mechanical properties, the following are its main mechanical properties:

Tensile strengthlow50-100 MPaenough to meet the requirements of the general packaging industry.
Yield strengthlowbelow 35 MPasoft and easy to process.
Elongationhigh5-30%For the packaging industry, it folds, wraps, and bends with ease.
Hardnesslow18-25HBsoft and easy to process.

Although its tensile strength and yield strength are low, its excellent physical and chemical properties make it widely used in packaging, electronics, and other fields.

Physical properties of 1235 aluminum

1. Density: 1235 aluminum foil has a density of about 2.7 g/cm³, and because aluminum has a lower density, it is lighter than other common metals.

2. Flexibility: 1235 aluminum foil is very flexible and can be easily folded, bent and wrapped around items without cracking or breaking. so, This also makes it ideal for use in the packaging industry.

3. Strength: Although 1235 aluminum foil is very soft, it still has a certain strength. Withstand certain tension and compression force, not easy to deform.

4. Thermal conductivity: Aluminum is an excellent thermal conductor, so 1235 aluminum foil has very good thermal conductivity, and can quickly transfer heat to the surface of objects, making it very effective in thermal protection.

5. Conductivity: Aluminum is also an excellent electrical conductor, so 1235 aluminum foil has good electrical conductivity and is widely used in the field of electrical and electronic products.

6. Corrosion resistance: Due to the high purity of aluminum in 1235 aluminum foil, it has very good corrosion resistance and is not easily oxidized or corroded. This makes it ideal for use in areas such as food packaging and pharmaceutical packaging.
