Aluminum and its alloys are widely used in various industries due to their excellent properties such as lightweight, corrosion resistance, and high strength-to-weight ratio. However, to enhance these properties and ensure the quality of aluminum products, surface treatment is crucial. Treatment additives play a significant role in this process by improving the effectiveness of aluminum surface treatment. This article will delve into the benefits of using treatment additives in aluminum processing, including their role in enhancing surface quality, promoting subsequent processing, and reducing energy consumption.
Treatment additives, particularly alkali etching additives, are commonly used in aluminum surface treatment. These additives primarily contain alkaline substances like sodium hydroxide or potassium hydroxide. They react with the oxide layer and impurities on the aluminum surface, effectively cleaning it and preparing it for further processing.
Alkali etching additives work by chemically reacting with the metal surface to dissolve the oxide layer and other impurities. This process not only cleans the surface but also enhances its reactivity, making subsequent treatments such as anodizing or coating more effective.
Treatment additives significantly improve the surface quality of aluminum by removing dirt and oxides, resulting in a smoother finish. This not only enhances the appearance of aluminum products but also improves the effectiveness of subsequent processing steps.

|---|---|
| Rough Surface | Smooth Surface |
By enhancing surface reactivity, treatment additives facilitate uniform and dense oxide layer formation during processes like anodizing. This improves the corrosion resistance and mechanical properties of aluminum products.

| Process | Without Additives | With Additives |
|---|---|---|
| Anodizing Time | Longer | Shorter |
| Energy Cost | Higher | Lower |
Treatment additives also contribute to enhanced corrosion resistance by ensuring a uniform and dense oxide layer. This is particularly important in applications where aluminum is exposed to harsh environments.

Treatment additives are essential in various aluminum processing applications, including:
- Aerospace Industry: For enhancing corrosion resistance and mechanical properties of aluminum alloys used in aircraft components.
- Automotive Industry: To improve the durability and appearance of aluminum parts in vehicles.
- Construction: For treating aluminum used in building facades and structural components.
In the automotive sector, treatment additives are used to enhance the performance of aluminum alloys in vehicle bodies and engine components. This not only improves fuel efficiency due to reduced weight but also enhances durability by increasing corrosion resistance.
