Overview of 1-Series Aluminum Foils in Relation to Carbon Coating Applications (1050, 1060, 1100)

1050 Aluminum:

1050 aluminium is a pure aluminium with an aluminium content of more than 99.5% and very low levels of other elements. It has high electrical conductivity and is an excellent conductive material. It also has good molding properties and can be processed and formed by cold and hot working.

Applications: 1050 aluminum is commonly used in applications that require high conductivity and corrosion resistance, such as battery manufacturing, capacitors, transformers, lighting fixtures, etc.

1060 Aluminum:

1060 aluminium is also a pure aluminium with an aluminium content of more than 99.6% and a small amount of copper. Alloy 1060 has properties similar to Alloy 1050, including high electrical conductivity and good formability. It can also be processed and shaped by cold and hot working.

Application: Alloy 1060 is commonly used in battery manufacturing, capacitors, food packaging, building materials and other fields, especially in applications with high purity requirements.

1100 Aluminum:

1100 aluminium is also a pure aluminium alloy with an aluminium content of more than 99.0% and small amounts of copper, iron and silicon. Alloy 1100 has good plasticity and high purity, and it can be processed and formed by cold and hot working. Alloy 1100 has relatively low strength but good corrosion resistance.

Application: Alloy 1100 is widely used in battery manufacturing, food packaging, building materials, heat exchangers, pressure vessels and other fields.

Surface Treatment

In the manufacturing process of carbon coated aluminum foil, the surface treatment of the aluminum foil substrate is an important step to provide good adhesion and surface properties to facilitate the subsequent coating process. Common surface treatment methods include chemical cleaning, electrolytic treatment, etc.

Chemical cleaning: Chemical cleaning is one of the commonly used surface treatment methods, which can remove impurities, grease, and oxides from the surface of aluminum foil to provide a clean surface. The process usually involves the following steps:

1. Alkali Cleaning: Aluminum foil is soaked in an alkaline solution, which can remove grease and some organic contaminants.

2. Acid Cleaning: Aluminum foil is soaked in an acidic solution, which removes oxides and other inorganic contaminants.

3. Rinsing: The cleaned aluminum foil needs to be rinsed thoroughly to remove residual chemicals and ensure a clean surface.

Electrolytic Treatment: By applying an electric current to the aluminum foil in the electrolyte, the finish and properties of the aluminum foil surface can be improved, providing better coating adhesion.

Mechanical treatment: Use mechanical methods, such as rolling, polishing, etc., to treat the surface of the aluminum foil to improve the surface finish and flatness, providing a better benchmark for the coating.

Coating Application

After the surface treatment of the aluminum foil substrate, the manufacturer of carbon coated aluminum foil usually coats the surface of the aluminum foil with a layer of carbon material. Coatings can be applied by different methods such as coating, spraying, printing, etc. The purpose of the coating is to provide electrical conductivity and protection to improve the properties of the aluminum foil.

The coated foil needs to be dried and cured to ensure that the coating adheres firmly to the surface of the foil. This is usually done by drying or heat treatment to allow the coating to form a stable structure that prevents the coating from detaching.

The aluminum foil substrate, surface treatment, and carbon coating are all crucial aspects in the production of carbon coated aluminum foil. The substrate serves as the base material, while surface treatment prepares the substrate for proper adhesion, and the carbon coating imparts specific properties and functionalities.

The aluminum foil substrate needs to possess specific properties like good conductivity, durability, and compatibility with the intended application. The selection of the appropriate substrate ensures the desired performance and functionality of the carbon coated foil.

Surface treatment before applying the carbon coating involves cleaning and modifying the surface to ensure proper adhesion and the elimination of contaminants. Surface treatment enhances the bonding between the substrate and the carbon coating, ensuring a uniform and reliable coating layer.
