Aluminum Round Tube

Aluminum round tubes are widely used in various industries and come in different forms and applications. Their main feature is the circular cross-section, and they are commonly used for structural support, frame construction, and other manufacturing fields. The manufacturing process, surface treatment, and the different types of aluminum alloy compositions make aluminum round tubes highly versatile in various applications.

Aluminum Round Tube Available Grades

Aluminum round tubes can be produced using a variety of aluminum alloys, with different alloy types offering different mechanical properties, corrosion resistance, and suitability for various applications. Common aluminum round tube alloys include:

Aluminum Round Tube 6061

6061 aluminum alloy round tube is a high-strength aluminum alloy with excellent weldability and good corrosion resistance. It is commonly used in various structural and mechanical components, and is widely applied in aerospace, automotive, marine, and construction industries for structural frames and load-bearing components. Its high strength makes it perform exceptionally well in applications that require withstanding significant pressure.

Aluminum Round Tube 6063

6063 aluminum alloy round tube is primarily used in the construction industry, offering good corrosion resistance and workability. It is widely used for frames, doors and windows, and decorative applications. With superior surface treatment properties, it is commonly seen in interior and exterior decorative projects, providing excellent aesthetics and durability. It is suitable for lightweight structures and applications with high aesthetic requirements.

Aluminum Round Tube 2024

2024 aluminum alloy round tube offers extremely high strength and good heat resistance, making it widely used in aerospace and high-strength structural fields. It is particularly suitable for aerospace components under high stress, such as aircraft fuselage, wing beams, and other high-performance structures. Although its corrosion resistance is relatively weak, it can be improved for use in harsh environments through proper surface treatment.

Aluminum Round Tube 6060

6060 aluminum alloy round tube is primarily used in construction and structural applications, offering good workability and corrosion resistance. It is commonly used in lightweight frame structures, piping systems, exterior decoration, and other engineering projects. Its good workability makes it suitable for various machining, cutting, and welding needs, and it is commonly found in construction, transportation, and industrial equipment.

Aluminum Round Tube Surface Treatments

Anodized Aluminum Round Tube

Anodizing is an electrochemical process that forms a protective layer on the surface of aluminum, significantly enhancing its corrosion resistance and surface hardness. This treatment is commonly used in environments requiring extra protection, particularly in outdoor applications or those exposed to harsh climatic conditions, such as building facades, marine equipment, and aerospace industry. The anodized layer also provides a wide range of color choices, increasing aesthetic appeal, while offering good wear resistance and scratch resistance.

Coated Aluminum Round Tube

Spraying and coating treatments improve the appearance and corrosion resistance of aluminum round tubes by applying various coatings. This process not only meets specific color requirements but also increases the protective layer of the surface, resisting chemical corrosion, UV radiation, and moisture penetration from external environments. It is commonly used in furniture, transportation, electronics, and other fields, providing rich visual effects and enhancing long-term durability.

Mill Finish Aluminum Round Tube

The mill finish surface refers to the aluminum round tube without any additional surface treatment, retaining the raw appearance of the aluminum material. Since it has not undergone polishing or anodizing, this surface treatment is simpler and more cost-effective, suitable for general industrial structures, piping systems, and low-cost applications. Although the corrosion resistance of mill finish is inferior to anodized or coated finishes, it can still meet the needs of many non-demanding environments.

Aluminum Round Tube Manufacturing Process

Aluminum round tubes are primarily produced through two manufacturing methods. Below is a comparison table between extruded aluminum round tubes and drawn aluminum round tubes:

Extruded Aluminum Round Tube

Extruded aluminum round tube is formed by forcing heated aluminum alloy billets through a mold, creating a continuous tube with a round cross-section. The surface of the extruded tube is usually rough and is typically supplied in a mill finish (unpolished).

The advantage of extruded aluminum round tubes is their relatively low manufacturing cost, making them suitable for general structural requirements in a wide range of applications.

Drawn Aluminum Round Tube

Drawn aluminum round tube is typically seamless, produced by drawing the billet through a mold to create a finer, seamless tube. While the manufacturing cost is higher, drawn tubes offer greater precision and are ideal for applications with more stringent requirements.

Drawn aluminum round tubes have smooth inner walls and uniform outer surfaces, making them commonly used in industries that demand higher precision and surface quality.

Applications of Aluminum Round Tube

• Construction Industry: Used for door and window frames, support structures, railings, fences, etc.
• Furniture Industry: Used for furniture frames, brackets, tables, chairs, etc.
• Automotive Industry: Used for vehicle body structures, frame components, and accessories.
• Machinery Industry: Used in machinery as structural supports, transmission components, and decorative materials.
• Aerospace: Certain high-precision applications may use drawn seamless aluminum round tubes.

Aluminum round tube is a versatile aluminum product that can be produced through extrusion or drawing processes, making it suitable for a wide range of structural applications. Depending on specific requirements, different aluminum alloys and surface treatments can be selected to meet the needs of various industries. The main advantages of aluminum round tube are its lightweight, high strength, corrosion resistance, and good machinability, making it widely used in construction, furniture, automotive, aerospace, and other fields.
