Round aluminum profiles have become increasingly popular due to their versatility, durability, and aesthetic appeal. Choosing the right alloy for these profiles is crucial to ensure optimal performance and longevity. This article will provide a comprehensive guide to selecting the best alloy for round aluminum profiles, considering various factors such as strength, corrosion resistance, and workability.


The strength of an aluminum profile is primarily determined by the alloy used. For round aluminum profiles, some of the most commonly used alloys include:

– 6061: This alloy offers excellent strength, with a tensile strength of 20,000 psi to 24,000 psi. It is a good choice for applications that require high strength and durability, such as structural frames and machinery components.

– 6063: Similar to 6061, 6063 offers high strength, with a tensile strength of 22,000 psi to 26,000 psi. Its higher alloy content makes it more corrosion resistant than 6061, but also slightly less machinable.

– 7075: This alloy is known for its exceptional strength, with a tensile strength of 50,000 psi to 83,000 psi. It is often used in aircraft components, automotive parts, and other applications where extreme strength is required.

Corrosion Resistance

Corrosion resistance is another important factor to consider when choosing an alloy for round aluminum profiles. Aluminum alloys that contain higher amounts of magnesium and manganese exhibit better corrosion resistance. Common alloys with good corrosion resistance include:

– 5052: This alloy contains a high amount of magnesium, which enhances its corrosion resistance. It is commonly used in marine applications, food processing equipment, and outdoor architectural elements.

– 6005: Similar to 5052, 6005 has a high magnesium content, resulting in excellent corrosion resistance. It is a good choice for applications exposed to harsh environments, such as chemical processing plants and coastal areas.

– 7020: This alloy contains both magnesium and manganese, providing exceptional corrosion resistance. It is often used in marine applications, architectural components, and transportation equipment.


Workability refers to the ease with which aluminum profiles can be machined, extruded, and formed. Alloys that are more workable are more versatile and can be used in a wider range of applications. Some of the most workable alloys include:

– 1100: This alloy is known for its excellent workability and is often used in sheet metal applications, such as building facades and roofing.

– 1235: Similar to 1100, 1235 offers high workability and is often used in automotive and aerospace components.

– 3003: This alloy balances workability with corrosion resistance, making it suitable for applications in the construction, automotive, and electronics industries.


Choosing the best alloy for round aluminum profiles requires careful consideration of the desired strength, corrosion resistance, and workability. By understanding the characteristics of different aluminum alloys, you can make an informed decision that will ensure optimal performance and longevity for your application. Remember to consult with an experienced aluminum supplier or manufacturer to discuss your specific requirements and find the alloy that best meets your needs.
