Classification and price of anodized aluminum plates

At present, the processing technology of anodized aluminum plates is generally divided into brushed anodized aluminum plates, anodized treatment, coloring oxidation treatment and polishing oxidation treatment. The most common coloring oxidation treatment and anodizing treatment processes are used frequently and the prices are also relatively high. Commonly used anodized aluminum plates/aluminum coils: 5052 anodized aluminum plates, 3003 anodized aluminum plates, 6061 anodized aluminum plates, 1060 anodized aluminum plates, and so on.

Classification of anodized aluminum plates

• 1. Cast-rolled anodized aluminum plates

Cast-rolled anodized aluminum plates refer to aluminum plates made of cast-rolled aluminum plates. Generally, the raw materials will use 3003 aluminum plates, 1060 aluminum plates, 8011 aluminum plates, etc. as the main casting materials. Secondly, some aluminum plates with low requirements such as 1100 aluminum plates will also be selected as raw materials for cast-rolled anodized aluminum plates, but the frequency of use is relatively low. The advantages of this type of aluminum plate are low material cost, low price, and high profit.

• 2. Hot-rolled anodized aluminum plate

Hot-rolled anodized aluminum plate is generally used as the main raw material. This type of aluminum plate is usually used by high-end customers or customers who need deep drawing. The more common raw materials are generally 5052 aluminum plate, 6061 aluminum plate, and hot-rolled 3003 aluminum plate. However, with the gradual increase in the use of hot-rolled aluminum plates and the insufficient supply of product output, the price and cost of hot-rolled anodized aluminum plates are high, but the oxidation effect of hot-rolled aluminum plates is also relatively good.

• 3. Anodized aluminum plate

The surface of the aluminum plate processed by the anodized aluminum plate process will have an oxide layer, which can not only increase the life of the aluminum plate, improve the performance of the aluminum plate, but also increase the area of ​​the aluminum plate and the product. The cost price of anodized aluminum plate is still relatively high, but it is also the most commonly used product at present.

• 4. Coloring oxidation aluminum plate

Coloring oxidation aluminum plate is a new type of aluminum plate processing, which is mainly used in high-end home appliances or some high-end furniture and building materials. Its cost is much different from the conventional aluminum plate spraying or rolling process, and the oxidation effect is also extremely different. The more common applications are power banks, mobile phone shells, TV shells or car interior decoration. This light density and stable quality anodized aluminum plate is mainly used.

Difference between anodized aluminum plate and ordinary aluminum plate

Ordinary aluminum plate and anodized aluminum plate are both aluminum plate decorations that are widely used in our daily life. The difference between anodized aluminum plate and ordinary aluminum plate is that anodized aluminum plate is a deep processing upgrade of ordinary aluminum plate.

• 1. Difference in service life

The life of the oxidized aluminum plate is longer than that of the conventional ordinary aluminum plate. Because the aluminum plate will form a thin oxide layer after oxidation, whether it is used outdoors or in a specific environment, its life is longer than that of ordinary aluminum plate, and the price of anodized aluminum plate is also higher than that of ordinary aluminum plate. The oxide layer forms a subtle barrier protective layer between the anodized aluminum plate and the aluminum plate. Ordinary aluminum plate can effectively extend the life of the metal surface after oxidation. If the surface of the anodized aluminum plate is coated, the anodized aluminum plate can be more wear-resistant and have a longer life than ordinary aluminum plate.

• 2. Difference in processing performance

After ordinary aluminum plate is processed, the processing performance and corrosion resistance of the anodized aluminum plate are better than those of ordinary aluminum plate. For example, under the same environment, the lifespan of ordinary aluminum plates and anodized aluminum plates are different. The rust resistance and corrosion resistance of oxidized aluminum plates are much better, about twice as good, especially for outdoor use.

• 3. Difference in surface quality

Anodized aluminum plates have better surface flatness, better adhesion, softer surface gloss, and delicate feel than ordinary aluminum plates. In our daily use, it is not only because the surface is added with an oxidized coating. In the process of using the overall anodized aluminum plate, it has better performance for direct stamping and direct plating of the finished product with an oxidized film. Therefore, after oxidation, ordinary aluminum plates can not only have a delicate surface, but also improve the overall oxidation quality of the aluminum plate.

Factors affecting the price of anodized aluminum plates

There are actually many factors that determine the price of one square meter of anodized aluminum plates, and there are actually many factors that can play a decisive role. For example, changes in the market environment and fluctuations in aluminum prices will cause fluctuations in the price of anodized aluminum plates.

✅1. Aluminum price factors.

The impact is relatively large, and it is also the main factor causing the price of one square meter of anodized aluminum plates. In the current environment, the demand for anodized aluminum plates may increase in the later period, so the influence of the price of aluminum ingots is more critical and important.

✅2. The processing fee factor of aluminum ingots to aluminum plates.

The price composition of anodized aluminum plates generally consists of three main factors: aluminum ingot price + aluminum plate processing fee + aluminum plate aluminum plate fee. The sum of these three factors is the price of one square meter or even one ton of anodized aluminum plates. However, with the fluctuation of aluminum plate processing fees, more and more aluminum plate processing fees have begun to rise gradually. The more commonly used raw materials for aluminum plates: 1100 aluminum plate, 1060 aluminum plate, 5052 aluminum plate, etc. have all experienced a certain degree of floating and fluctuation this year.

✅3. Anodized aluminum plate processing fee factor.

The demand for aluminum plates will be an increasing or gradually increasing upward trend in the future. Especially for the current market environment, aluminum plates themselves have the advantages of low density and good heat dissipation performance. The process of anodized aluminum plates can further improve the performance of products.
