How to Choose the Right Aluminum Profiles? - CHAL

Aluminum profiles can be processed from various types of aluminum materials. Depending on the aluminum type used, the characteristics of the processed aluminum profiles will vary. So, how do you choose the right aluminum profile for your needs?

What is an Aluminum Profile?

Aluminum is a silvery white metal. In humid air, it can form an oxide film that prevents metal corrosion, with a relative density of 2.7g/cm³, a melting point of 660°C, a boiling point of 2327°C, high specific strength, good electrical and thermal conductivity, high reflectivity, and oxidation resistance. Therefore, aluminum is an excellent match for finished materials. These aluminum parts, including windows and radiator fins, are called aluminum profiles.

Aluminum profiles are aluminum tube materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The forming process of aluminum profiles mainly includes five processes: casting, extrusion, cutting, CNC washing and cutting, surface pretreatment, and coloring.

What are the Types of Aluminum Profiles?

Aluminum profiles can be processed from any type of aluminum, ranging from 1-series to 7-series aluminum as raw materials for aluminum profiles. Accordingly, they correspond to aluminum profiles of different grades based on their properties.

Aluminum profiles are often referred to in “grades” based on the aluminum series and alloy composition.

• 1100 Aluminum: Ideal for corrosion-resistant profiles requiring no high rigidity, such as storage containers, sheet metal workpieces, heat exchangers, printing plates, and more.
• 2011 Aluminum: Suitable for free-cutting alloys with excellent machinability and high strength, but poor corrosion resistance, used in machining products requiring good cutting performance.
• 3003 Aluminum: Combines properties of 1xxx series with higher strength, used for food and chemical storage, tanks, pressure vessels, and pipelines.
• 4A01 Aluminum: Suitable for construction materials, machine parts, and welding materials due to its high silicon content and wear resistance.
• 5052 Aluminum: Represents medium-strength alloys with good corrosion resistance, weldability, and formability, ideal for aircraft fuel tanks, street lamp brackets, and hardware products.
• 6061 Aluminum: Known for high corrosion resistance, suitable for the production of screws, ships, and vehicles.
• 6N01 Aluminum: A medium-strength extrusion alloy, good for large-scale profiles with complex shapes, used in vehicles and ships.
• 6063 Aluminum: A representative alloy for extrusions, lower strength than 6061, suitable for profiles with complex cross-sectional shapes, used in highway guardrails, vehicles, and furniture.
• 7072 Aluminum: Used for corrosion-resistant coverings and heat exchanger fins.
• 7075 Aluminum: One of the strongest aluminum alloys, used for aircraft, ski poles, and thick plate forgings.

Main Applications of Aluminum Profiles

1. Architectural profiles (doors, windows, curtain walls).
2. Radiator profiles.
3. General industrial profiles: Used in automated machinery and equipment, customizable by mold opening.
4. Profiles for rail vehicle structures: Used in rail vehicle bodies.
5. Decorative profiles: Used as face frames, mounting various decorative paintings.
6. Appearance profiles: Used in home appliances or communication industries, such as mobile hard disks and TV sets.
