Ⅰ-b: 5052 Anodized Aluminum Introduction
5052 anodized aluminum is an aluminum-magnesium alloy, which has become one of the most widely used alloys due to its good processability and corrosion resistance. 5052 anodized aluminum is anodized to improve coating adhesion and corrosion resistance, with good surface quality and stable performance.
5052 aluminum alloy has exceptional anodizing quality and is capable of meeting common color needs. Its surface processing quality is outstanding and can be processed into a variety of different textures.

Ⅰ-c: 5052 Anodized Aluminum Applications
1. Pre-polished/mirror-finished can also be applied in coil and sheet form, so no additional finishing steps are required, so it is ideal for larger electronics such as laptops and TVs.
2.The main alloying element of 5052 anodized aluminum plate is magnesium, which has good formability, corrosion resistance, weldability, and medium strength. And rivets, hardware products, electrical enclosures, etc.

Ⅰ-e:Characteristics of 5052 Anodized Aluminum Sheet
1. Corrosion resistance. The 5052 anodized aluminum plate can effectively protect the aluminum substrate from corrosion. The anodized film is obviously better than the naturally formed oxide film. The film thickness and sealing quality directly affect the performance.
2. Hardness and wear resistance. The hardness of the 5052 anodized aluminum plate is much higher than that of the aluminum substrate. The hardness of the substrate is HV100, the hardness of the ordinary anodized film is about HV300, and the hard oxide film can reach HV500. The relationship between wear resistance and hardness is consistent.
3. Decorative. Aluminum anodized film protects the metallic luster of the polished surface, anodized film color, and obtains and maintains a colorful appearance.
4. Adhesion of organic coating and electroplating layer. 5052 anodized aluminum plate is a method for the aluminum surface to receive organic coatings and electroplating layers, which effectively improve the adhesion and corrosion resistance of the surface layer.
5. Electrical insulation. Aluminum is a good conductor, and 5052 anodized aluminum plate is a high-resistance insulating film. The dielectric breakdown voltage is greater than 30V/m, and the specially prepared high insulating film even reaches about 200V/m
6. Transparency. The transparency of the aluminum anodized film itself is very high, and the higher the purity of aluminum, the higher the transparency. Both the purity and alloy composition of the aluminum alloy material have an impact on transparency.
7. Functionality. Various functional materials can be obtained by depositing functional particles in the micropores by utilizing the porosity of the anodic oxide film. Functional component functions under development include electromagnetic functions, catalytic functions, sensing functions, and separation functions.
Ⅱ: Popular science: the process of anodized aluminum
Anodizing is an electrochemical process that transforms the surface of an aluminum sheet or coil into a decorative, durable, corrosion-resistant anodized finish. The aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is carried out under specific conditions and the action of an applied current.
The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, the thickness of which is 5-20 μm, and the hard anodized film can reach 60-200 μm. Anodized aluminum products have the characteristics of high hardness, good insulation, strong corrosion resistance and strong adsorption capacity.
