3003 Aluminum Foil Product Introduction
3003 aluminum foil is a commonly used product of AL-Mn series alloys. This product has good anti-rust properties, the strength is about 10% higher than 1100, and the formability, weldability, and corrosion resistance are all good. Used for processing parts that need good formability, high corrosion resistance and good weldability.

Quality Control of Aluminum Foil in Annealing Process
In order to make the quality of the aluminum foil meet the requirements of the technical surface, we will anneal the aluminum foil. Annealing treatment can control the mechanical properties and surface quality of aluminum foil. The annealing process is carried out after the aluminum foil is rolled to the finished thickness.
Aluminum foil is a rolled product, and the layers are close to each other. The composition of the lubricating oil used for rolling is relatively complex. After the finished product is annealed, the aluminum foil is often completely recrystallized, and the mechanical properties reach the standard. However, the rolling in the aluminum foil coil is also required. The oil is completely burnt out. Therefore, the annealing time of aluminum foil is relatively long. Sometimes due to the rolling oil in the aluminum foil coil, some components are oxidized and polymerized, producing complex polymers, or incomplete combustion, resulting in carbon residue and other reasons, resulting in oil marks or oil spots on the surface of the aluminum foil, causing pollution on the surface of the aluminum foil. scrapped.
Ways to eliminate pollution:
1. Select the appropriate rolling process lubricant
Improper selection or poor quality of base oils and additives are the root causes of surface contamination.
2. Prevent contamination of rolling oil
3. Use suitable annealing
