What are the common alloys of anodized aluminum circles?

Anodizing is a surface process for aluminum alloy materials. Generally speaking, all aluminum alloy grades can be anodized, but the surface effects after anodizing are different.

5000 series aluminum alloy is the most suitable aluminum alloy series for anodizing. The following are the anodizing effects of different series of aluminum alloys:

1000 series pure aluminum

This series of aluminum alloys is called pure aluminum. Aluminum in this series can be anodized. The resulting aluminum oxide layer is clear and somewhat shiny. Because the underlying pure aluminum is relatively soft, these anodized aluminums are easily damaged and lack mechanical properties compared to other series of aluminum alloys.

2000 series aluminum alloy

This series of aluminum alloys is AL-CU alloy. The copper in these alloys forms a very strong and hard aluminum alloy. While copper is useful for improving the mechanical properties of aluminum, unfortunately it makes these alloys unsuitable for anodizing. When anodized, 2000 series aluminum alloys have an oxide layer, which is a yellowish shade that is generally considered unattractive. Additionally, the layer produced by anodization provides poor protection for the underlying aluminum alloy.

3000 series aluminum alloy

Manganese alloyed aluminum belongs to this series. Although the anodized layer provides good protection for the manganese alloy aluminum substrate, it creates an undesirable brown color. Furthermore, this brown color is available on different substrates and especially in different grades. This makes it difficult to maintain similar colors on 3000 series aluminum components.

4000 series aluminum alloy

The 4000 series is made of aluminum-silicon alloy. Anodized 4000 material well protects the aluminum oxide layer produced by the anodizing process. However, it’s important to note that the 4000 Series has a dark gray color that lacks aesthetic appeal. 4000 Aluminum alloy is often used to weld other alloys such as 6000, but if these welded components are anodized, the weld metal will not match the color of the base metal.

5000 series aluminum alloy

This series refers to aluminum alloyed with manganese. After anodization, 5000 series alloys develop a strong, clear oxide layer. They are excellent candidates for anodizing, however, there are some important considerations during the anodizing process on 5000 series alloys. For example, certain alloying elements, such as manganese and silicon, need to be kept within a certain range; also, the anodizing process used is important. These alloys can often be welded with a 4000 series alloy in place of the weld filler metal so that the resulting weld is no different than other colors of anodized aluminum components.

6000 series aluminum alloy

The 6000 Series is designed for magnesium and silicon alloy aluminum. These alloys are excellent candidates for anodizing. The oxide film follows the anodizing process and is transparent and provides excellent protection. Because 6000 series aluminum alloy have good mechanical properties and are easy to anodize, they are often used in structural applications.

Difference between anodized aluminum discs and ordinary aluminum discs

Anodized aluminum circle: It is formed by generating a dense oxide film on the surface of aluminum plate through electrochemical principle. Anodized aluminum discs are obtained by stamping anodized aluminum discs. The following are the differences between anodized aluminum circles and ordinary aluminum discs:

Significant improvement in appearance quality

Compared with ordinary aluminum discs, the production process of anodized aluminum discs is more exquisite, so its surface smoothness and flatness are much more than that of ordinary aluminum discs. Whether it is light refraction or color fullness, anodized aluminum discs show better performance.

Rich colors and good decoration

Compared with ordinary aluminum discs with a single gray color, anodized aluminum circles have a richer choice of colors. This is due to the oxidation coloring method of anodized aluminum discs, which not only meets various design requirements, but also gives the building a stronger visual impact.

Long service life and high durability

Due to the fact that anodized aluminum circles have a dense oxide film on their surface, they offer excellent rust resistance and a relatively longer service life. Moreover, this oxidized coating also makes the surface of the material more wear-resistant.

Excellent processing performance

The anodized aluminum circle sheet can be folded and bent, which is much better than the machinability of ordinary aluminum circle sheet. Manufacturers can make products of different specifications and sizes according to the demand, and they can be used normally under various climatic conditions.

Better environmental performance

Anodized aluminum circles use fewer chemicals in the manufacturing process and the residue has less impact on the environment, making it a more environmentally friendly product category.

More Cost Effective

Although the manufacturing cost of anodized aluminum circles is slightly higher than that of regular aluminum circles, the overall cost-effectiveness is actually higher considering its superiority in terms of longevity, weathering resistance, etc.

High corrosion resistance

As the aluminum oxide layer formed by the anodic oxidation process is highly airtight, anodized aluminum discs are highly resistant to acids, alkalis, salts and other media, and are more capable of coping with a wide range of environmental conditions than ordinary aluminum discs.

Good insulation

Anodized aluminum discs have excellent electrical insulation properties, with high resistance values, which gives them an advantage in applications where electromagnetic interference is a concern, such as in the packaging of electronic equipment.

Enhanced surface hardness

The aluminum oxide layer formed after anodizing is like a layer of hard armor for the aluminum plate, which greatly enhances the surface hardness and improves the resistance to abrasion and impact, thus prolonging the service life of the material.

Easy to clean and maintain

The surface of anodized aluminum discs is dense and smooth, with good self-cleaning properties. Ordinary stains or dust can be easily removed, and even prolonged outdoor exposure will not cause surface damage or pollution, greatly reducing the workload of cleaning and daily maintenance.

Casting production process and its introduction

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.

Hot rolling production process and its introduction

  • 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
  • 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
  • 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
  • 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
    • Hot rolling equipment

      Casting and rolling process

      Casting and rolling process: liquid metal, front box (liquid level control), casting and rolling machine (lubrication system, cooling water), shearing machine, coiling machine.

      • 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
      • 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
      • 3. The production speed is generally between 1.5m/min-2.5m/min;
      • 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
        • Cold rolling production process

          • 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
          • 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
          • 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
          • 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
            • Casting rolling

              Introduction to finishing production process

              • 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
              • 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
              • 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.

Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxic, easy to recycle, excellent electrical conductivity, heat transfer and corrosion resistance, so it has a wide range of applications.
