3003 Aluminum Coil

It has good corrosion resistance and also has good corrosion resistance in dilute acids. In daily life, we can use 3003 aluminum rolls to make common wine bottle caps, beverage bottle caps, cosmetic caps, etc.
Market application of 3003 aluminum coil
It is mainly used in battery shell materials, lighting, interior decoration, air conditioning tubes, automobile fuel tanks, Electrolytic capacitor and other fields.
Performance advantages
Advantages of 3003 aluminum coil products：
1. 3003 aluminum coil has good forming and processing characteristics, high corrosion resistance, good weldability and conductivity, and higher strength than 1100 aluminum coil;
2. 3003 aluminum coil has excellent rust prevention characteristics and is a widely used rust prevention aluminum; Smooth surface, good plasticity, and pressure resistance;
3. The power battery casing is made of 3003 aluminum coil, which is impact resistant, not easy to crack and leak, and can meet the strength and rigidity requirements of the power battery casing
The reason for corrosion of insulated aluminum coils: Corrosive oxidation refers to the incomplete contact between the surface of the aluminum coil and air, and the lack of maintenance layer due to the packaging state of the coil before use. In this situation, if the aluminum coil enters water, is exposed to rain or moisture, the moisture in the moisture will stop chemical reaction with the surface of the aluminum coil, forming corrosion of the aluminum coil. After corrosion, the aluminum coil will show corrosion marks, and the fierce condition will turn black and black, It’s like being burned by fire. But after this corrosion occurs, there will be no secondary damage to the aluminum coil. The aluminum coil itself is not a problem, only the appearance is damaged.
How to prevent oxidation and corrosion of insulation aluminum coils?
1. Aluminum rolls should not be placed on the roofs of workshops and warehouses in areas with rain or snow leaks.
2. Strengthen the management of air dryness and ensure that there is no water in the compressed air.
3. The packaging of aluminum foil rolls should be sealed, and an appropriate amount of desiccant should be added to each roll.
4. When transporting from a low-temperature area to an area with high temperature and humidity, do not immediately open the sealed packaging.
5. Strengthen the management of rolling oil and control its water content below 0.04%.
6. The humidity of the wooden shaft and board of the packaging box shall not exceed 18%, and the temperature of the colored aluminum coil for packaging shall not exceed 45 ℃.
Normal oxidation refers to the complete contact between the surface of the aluminum coil and air after use, such as wrapping it on a pipeline, forming a layer of oxide film. This layer of oxide film will maintain the aluminum coil from further corrosion, so even if it is exposed to rain or outdoor sunlight after use, the insulation aluminum coil will not corrode.
