Color anodizing and ordinary anodizing each have their own characteristics in terms of durability, but which one is more durable needs to be evaluated based on specific application scenarios and requirements

1、 Durability of ordinary anodizing

Ordinary anodizing significantly improves the corrosion resistance, wear resistance, and hardness of metals by forming a dense layer of aluminum oxide film on the metal surface. This oxide film has good chemical stability and physical properties, and can resist external environmental erosion and damage to a certain extent. Therefore, metal products treated with ordinary anodizing can exhibit good durability in various environments

2、 Durability of Color Anodizing

Color anodizing, based on ordinary anodizing, presents rich color effects on the oxide film through process steps such as dyeing and sealing. Meanwhile, these process steps further enhance the density and corrosion resistance of the oxide film. Metal products treated with color anodizing not only have a beautiful appearance, but also exhibit durability similar to ordinary anodizing while maintaining color

However, it should be noted that the durability of colored anodizing may be affected by dyeing and sealing processes. If the selection of dyeing or sealing agents is improper, or if the process parameters are not strictly controlled, it may lead to color fading or reduced corrosion resistance of the oxide film. Therefore, when performing color anodizing treatment, it is necessary to choose appropriate dyes and sealing agents, and strictly control the process parameters to ensure that the treated metal products have good durability

3、 Comprehensive comparison

In most cases, both colored anodized and ordinary anodized metal products have good durability. However, if we only look at the performance of the oxide film itself, ordinary anodizing may focus more on improving the corrosion resistance, wear resistance, and hardness of the metal; Color anodizing not only maintains these properties, but also endows metals with unique color effects

In practical applications, the choice of anodizing method depends on the specific application scenario and requirements. If there are high requirements for the appearance of the product and it is necessary to maintain long-lasting color without fading, then colored anodizing may be a better choice; If more emphasis is placed on the corrosion resistance, wear resistance, and hardness of the product, then ordinary anodizing is also a reliable choice

In summary, both colored anodizing and regular anodizing have advantages in durability, and which one is more durable needs to be evaluated based on specific requirements
