3105 Aluminum Foil

In the food packaging industry, 3105 aluminum foil is often used to make packaging materials for products such as dairy products, confectionery, and processed foods. Its excellent barrier properties help to keep food fresh and prevent contamination. It is also commonly used in the automotive industry for applications such as heat exchangers and fuel tanks, and in the construction industry for roofing and siding.

It has the following characteristics:

 

1、Tensile strength: The tensile strength of 3105 aluminum foil typically ranges from 145-185 MPa (21-27 ksi). This refers to the amount of force required to pull the foil apart along its length.

 

2、Yield strength: The yield strength of 3105 aluminum foil typically ranges from 85-115 MPa (12-17 ksi). This refers to the amount of stress that can be applied to the foil before it starts to deform.

 

3、Elongation: The elongation of 3105 aluminum foil typically ranges from 5-12%. This refers to the amount that the foil can stretch before it breaks.

 

4、Hardness: The hardness of 3105 aluminum foil typically ranges from 40-60 HB. This refers to the resistance of the foil to indentation or scratching.
