Aluminum strips can be classified by many aspects, such as alloy, surface treatment process, size and use, etc., aiming to give you a clearer understanding of aluminum strips.
The raw materials of aluminum strip (Aluminum strip/Aluminum strip) are pure aluminum or aluminum alloy cast-rolled aluminum coils and hot-rolled aluminum coils. They are rolled by a cold rolling mill into thin aluminum coils of different thicknesses and widths, and then slit according to the purpose. The machine cuts longitudinally into aluminum strips of different widths.
Aluminum strips have the advantages of light weight, high strength, and good corrosion resistance, and are widely used in various fields.
Aluminum strips are lightweight and high-strength. Compared to other metal materials, aluminum strips are lighter in weight but relatively stronger, making them ideal for manufacturing a variety of lightweight structures and equipment. Its high strength also makes the aluminum strip more resistant to wear and impact during application.
Aluminum strip has good corrosion resistance. Due to the protection of the oxide film on the surface, the aluminum strip can effectively prevent the occurrence of oxidation corrosion and reduce maintenance and upkeep costs. This makes aluminum strips widely used in chemical industry, electric power, communications and other fields to manufacture corrosion-resistant equipment and components.
The electrical and thermal conductivity properties of aluminum strips are also noteworthy. Aluminum strips have excellent electrical and thermal conductivity properties, making them widely used in electronic components, cables and wires.

5000 series aluminum strips: Mainly added with magnesium element, such as 5052, 5083, 5754 aluminum strips, etc. This series of aluminum strips have good corrosion resistance, weldability and medium strength, and are widely used in ships, vehicles, tankers, and pressure vessels , bridge structures, curtain wall systems, etc.
6000 series aluminum strips: such as 6061 and 6063 aluminum strips, etc., contain magnesium and silicon, can be strengthened through heat treatment, have good comprehensive properties, and are widely used in building profiles, industrial frames, rail transit, etc.
8000 series aluminum strip: This series of aluminum strips sometimes add iron and other alloy elements, such as 8011 aluminum strip, which is mainly used for pharmaceutical foils, beer caps, cable foils, core materials of composite materials, etc.
Aluminum strips have the advantages of light weight, high strength, and corrosion resistance, so they are widely used in various fields.
Aluminum strips are also classified according to different applications, such as aerospace aluminum strips, construction aluminum strips, automotive aluminum strips, etc.
Aluminum strips for aerospace use need to have excellent strength, rigidity and heat resistance; aluminum strips for construction need to have good weather resistance and corrosion resistance; aluminum strips for automobiles need to have lower density, high strength and excellent Forming performance, etc.

Aluminum strips can also be further classified according to surface treatment methods. The main purpose is to improve the corrosion resistance, wear resistance, aesthetics and meet specific functional requirements of the aluminum strips. The following are some common surface treatment processes for aluminum strips:
Anodizing is an electrolytic oxidation process that significantly improves its corrosion resistance and wear resistance by forming a dense aluminum oxide film (Al₂O₃) on the surface of the aluminum strip. It can also be dyed to achieve various color effects.
By placing the aluminum strip in an electrophoresis tank and energizing it, a resin film is deposited on the surface. The resulting coating is smooth and has strong adhesion, which not only provides excellent anti-corrosion protection, but also gives the aluminum strip an excellent decorative effect.
Electrostatic powder spraying uses high-voltage electrostatic adsorption of powder coating on the surface of an aluminum strip, and then solidifies it at high temperature to form a coating. It has high mechanical strength and weather resistance, rich colors and is environmentally friendly.
The fluorocarbon spraying process uses fluoropolymer coatings to form a coating with extremely high weather resistance, corrosion resistance and self-cleaning properties. It is especially suitable for surface treatment of aluminum strips in long-term outdoor exposure environments.
Brushing can give the aluminum strip a delicate texture, showing a satin or hairline effect, increasing texture; polishing can make the surface of the aluminum strip achieve a mirror effect with extremely high gloss.
By high-speed jetting of sand particles onto the surface of the aluminum strip, the surface oxide layer is removed and a micro-rough surface is formed, which can achieve a matte or frosted effect and enhance the visual effect and feel of the product.
Aluminum strips are electroplated with a layer of other metals, such as zinc, chromium, nickel or other alloys, to improve their appearance, wear resistance and corrosion resistance.
It includes steps such as degreasing, pickling, and chemical conversion treatment to remove grease and oxide layers on the surface of the aluminum strip and improve the quality of subsequent coating or anodizing processes.
A layer of plastic film or metal film can be laminated or vacuum evaporated on the surface of the aluminum strip to provide additional protection or special visual effects.
