Types of anodizing
Ordinary Anodizing (Type I, Chromic Acid Anodizing)
Uses chromic acid for oxidation treatment, resulting in a thinner oxide layer (approximately 0.5-2μm). It is mainly used in fields requiring high dimensional precision, such as aerospace, offering some corrosion resistance but lower wear resistance.
Hard Anodizing (Type III, Hard Anodizing)
Uses higher voltage and low-temperature conditions to form a thicker oxide layer (up to 25-150μm), significantly enhancing wear resistance and hardness. It is suitable for high-strength applications such as mechanical parts, military equipment, and automotive components.
Thick Film Anodizing
Falls between ordinary and hard anodizing, with an oxide layer thickness generally ranging from 10-25μm. It offers good corrosion resistance and moderate wear resistance, widely used in industrial, construction, and electronic products.
Colored Anodizing
Involves dyeing after ordinary or thick film anodizing, offering a variety of colors such as black, gold, red, and blue. It is mainly used for decorative applications such as in construction, home furnishings, and electronic device enclosures.
What are the notable advantages of anodized aluminum tubes?
Corrosion resistance: The anodizing process forms a durable oxide layer on the surface of the aluminum tube, significantly enhancing its corrosion resistance. The oxide layer effectively resists environmental factors and chemicals, extending the tube's lifespan, especially in harsh conditions.
Increased surface hardness: The oxide layer formed during anodizing greatly increases the surface hardness of the aluminum tube, making it more wear-resistant than untreated aluminum. This increased hardness allows anodized aluminum tubes to perform excellently under mechanical friction and impact.
Scratch resistance: The surface of anodized aluminum tubes is smooth and hard, making it less prone to scratches. This scratch resistance ensures that the tube maintains its appearance and performance during transportation and use.
Colorability: After anodizing, the surface of the aluminum tube can easily be dyed to meet aesthetic and customization needs. This coloring not only enhances the appearance but also further improves the material's corrosion resistance.
Extended lifespan: Due to its excellent wear resistance, anodized aluminum tubes have a significantly extended service life, reducing the need for frequent replacements or maintenance, thus lowering overall operating costs.
