Several common production methods of black aluminum plates

What is Black Aluminum Sheet

Black aluminum sheet refers to an aluminum sheet that has a black effect after surface treatment. This type of aluminum sheet is processed through a series of surface treatment processes on the basis of the original aluminum material. It has a wide range of uses, including architectural decoration, furniture manufacturing, and home appliance panels. It can also be used as parts and components in industrial production and manufacturing.

Black Aluminum Sheet production process

Basic aluminum sheet production process

1. Ingredients and smelting:

According to the required alloy composition ratio, aluminum and other alloying element raw materials are accurately weighed and mixed, and then melted into liquid aluminum alloy in a smelting furnace.

2. Ingot molding:

Molten aluminum alloy is poured into a mold to form an ingot, which is then cooled, cut, and the surface oxide layer and impurities are removed.

3. Hot rolling/cold rolling:

After the ingot is homogenized, it is hot-rolled to reduce the thickness to a certain thickness, and then cold-rolled to further precisely adjust the thickness and flatness.

4. Preprocessing:

The rolled aluminum sheets are subjected to a series of surface treatments, including degreasing, cleaning, alkali washing (neutralization), etching and other steps to remove grease, oxides and other contaminants.

Black surface treatment process

1.Anodizing:

If anodizing technology is used to obtain a black aluminum sheet, an oxide film will be formed on the surface of the aluminum sheet, and then the film layer will be dyed black through a dyeing process, and finally sealed to enhance its weather resistance and wear resistance.

2.Painting:

Powder spraying, fluorocarbon spraying or paint spraying may be used to form a black coating on the surface of the aluminum sheet. For example, high-quality black fluorocarbon paint is used. After multiple sprays, it is cured in a high-temperature baking oven to form a strong and durable black paint surface.

3.Electrophoretic coating:

A uniform black resin film is deposited on the surface of the aluminum sheet through an electrophoresis process, which can provide excellent anti-corrosion and decorative effects.

4.Drawing and dyeing:

A black brushed aluminum sheet can be produced by mechanically drawing the aluminum sheet to form a texture and then dyeing it.

5.Composite process:

For composite materials such as aluminum-plastic panels, one or both sides of the aluminum panel may be covered with black plastic film or other coating materials to achieve the black effect.

Advantages of black aluminum sheets

• Aesthetic Appeal: Black aluminum sheets provide a sleek and modern appearance, adding a touch of elegance to architectural and design applications.
• Durability: Aluminum is inherently durable and resistant to corrosion, making black aluminum sheets suitable for outdoor and high-traffic areas.
• Lightweight: Aluminum is lightweight, making it easy to handle and install, which can be particularly advantageous for large-scale projects.
• Weather Resistance: Black aluminum sheets are weather-resistant and can withstand exposure to harsh environmental conditions, including UV radiation, moisture, and temperature fluctuations.
• Low Maintenance: Aluminum requires minimal maintenance, saving time and costs associated with upkeep.
• Recyclability: Aluminum is highly recyclable, making black aluminum sheets an environmentally friendly choice.
• Reflectivity: Black aluminum sheets can have high reflectivity, which can be beneficial for applications where heat reflection is desired.

Common applications of black aluminum sheets

1. Field of architecture： black aluminum sheets can be used to manufacture architectural curtain walls, roofs, doors, and other components. It has the characteristics of beauty, corrosion resistance, high strength, and can improve the energy efficiency of buildings.

2. Electronics field： black aluminum sheets can be used to manufacture electronic product casings, heat sinks, and other components. It has good heat dissipation performance and a pleasing appearance, which can enhance the quality and competitiveness of electronic products.

3. Automotive field： black aluminum sheets can be used to manufacture automotive bodies, doors, roofs, and other components. It has the characteristics of lightweight, high strength, corrosion resistance, and can improve the safety and energy efficiency of automobiles.

4. Aerospace field： black aluminum sheets can be used to manufacture the shells, heat sinks, engine parts, and other components of aerospace vehicles. It is lightweight, high strength, corrosion-resistant, and can enhance the performance and competitiveness of aerospace vehicles.

Different types of black aluminum sheets

Pricing and cost considerations for black aluminum sheets

The black aluminum plate is obtained by black treatment of the basic aluminum plate, so the price of the black aluminum plate is higher than that of the conventional aluminum plate of the same specifications.

The price of black aluminum plates is higher than that of conventional aluminum plates, but the prices of different types of black aluminum plates are also different. For example, the price of anodized black aluminum plates is higher than that of black painted aluminum plates because the anodizing process is relatively complex and costly.
