If you want to do aluminium foil container business, you need to understand aluminium foil container making raw material. Because in the field of aluminium foil container manufacturing, the choice of raw materials is crucial, which directly determines the quality.
Today, as an aluminum foil manufacturer, Zhengzhou Eming will introduce you to three alloys commonly used in aluminum foil container manufacturing: 8011, 3003 and 3004. We will take you to have a deep understanding of the uniqueness of these materials.
8011 alloy belongs to the aluminum-manganese alloy series. Its main alloying element is aluminum (Al), and it contains a small amount of iron (Fe) and silicon (Si). In the manufacturing of aluminum foil containers, 8011 alloy is one of the commonly used raw materials. It is usually supplied in O state (annealed state). In this state, 8011 alloy has good processing performance and can be easily processed into aluminum foil of various thicknesses during rolling. At the same time, its strength is moderate. For the general aluminum foil container manufacturing, it can not only meet the basic structural strength requirements, but also facilitate subsequent forming operations. In the field of food packaging, aluminum foil containers made of 8011 alloy are widely used in fast food boxes, baked food packaging, etc. Its good moisture resistance and certain barrier properties can effectively protect food from the influence of the external environment and extend the shelf life of food.
Alloy 3003 Aluminum Foil
3003 alloy is also based on aluminum, and the main alloying element is manganese (Mn), with a content of about 1.0%-1.5%. It is also commonly used in the manufacture of aluminum foil lunch boxes. The alloy is mostly used in the H18 state (work hardened state). The 3003 alloy in the H18 state has excellent corrosion resistance. Even in some more complex environments, it can remain stable for a long time and is not easily corroded. In terms of formability, the 3003 alloy performs well and can be processed into aluminum foil containers of various shapes through stamping, stretching and other processes. Whether it is a square lunch box with a regular shape or a special-shaped container with a unique shape, the 3003 alloy can easily cope with it. In the catering industry, aluminum foil containers made of 3003 alloy are often used to hold various sauces, seasonings, etc., and its corrosion resistance ensures the safety of the product during storage and use.
3004 Aluminium Foil
3004 alloy is an aluminum-manganese-magnesium alloy. In addition to aluminum and manganese elements, it also contains a certain amount of magnesium (Mg). Although the 3004 alloy has obvious advantages in the manufacture of large aluminum foil containers, it is relatively rarely used in the manufacture of aluminum foil trayes. However, it is also used in specific large-capacity and high-strength lunch boxes. Common states include H32 (stabilized state after work hardening). The addition of magnesium makes 3003 alloy have higher strength and toughness. In terms of strength, it can withstand greater pressure and weight and is not easy to deform; in terms of toughness, it is not easy to break even if it is subjected to a certain degree of external force impact. This characteristic makes 3004 alloy particularly suitable for manufacturing large aluminum foil containers, such as industrial containers and large-capacity food storage containers. In the fields of aerospace food supply, large-scale catering distribution, etc., aluminum foil containers made of 3004 alloy play an important role with their excellent performance.
