6061 aluminum profile buying guide & knowledge detailed

When choosing 6061 aluminum alloy profiles, in addition to understanding its basic characteristics, you also need to choose the appropriate alloy state, profile size, surface treatment and processing method according to specific application requirements. The following are key knowledge points and purchase recommendations about 6061 aluminum profiles to help you make more accurate purchasing decisions.

1. How to choose the appropriate 6061 aluminum profile?

When purchasing 6061 aluminum profiles, the following factors should be considered:

Alloy Temper—Common tempers of 6061 aluminum profiles include:

• T4: Good machinability and formability, suitable for applications requiring subsequent processing.
• T6: The hardness and strength are greatly improved after strengthening treatment, which is suitable for structural parts with high strength requirements.
• T651: Additional internal stress removal, more suitable for high-precision machining.

Profile specification & shape - Choose the appropriate shape according to application requirements, such as square tube, rectangular tube, T profile, H profile, C profile, radiator profile, etc.

Processing requirements - Is CNC machining, drilling, welding, bending, stamping and other subsequent processing required?

Surface treatment - Is anodizing, electrophoresis, spraying, sandblasting, etc. required to improve corrosion resistance or aesthetics?

2. 6061 aluminum profile vs other common aluminum profile alloys

Different aluminum alloy profiles are suitable for different application scenarios. The main advantages of 6061 are its comprehensive strength, machinability and corrosion resistance. However, in some specific fields, other alloys may be needed as substitutes:

6061 is the best aluminum alloy with comprehensive performance, suitable for industrial applications with high strength and good corrosion resistance, while 6063 is more suitable for construction and low-load scenarios, such as door and window frames.

3. Common misunderstandings of 6061 aluminum profiles

• Myth 1: 6061 aluminum profiles cannot be welded - In fact, 6061 is well weldable in the T4 state, and requires subsequent heat treatment to restore strength after welding in the T6 state.
• Myth 2: 6061 is as strong as steel - Although 6061 has a high strength-to-weight ratio, its absolute strength is still lower than steel and should be evaluated with caution in high-load situations.
• Myth 3: All 6061 profiles have the same performance - The performance of 6061 is affected by factors such as extrusion process, heat treatment, and impurity content. The manufacturer's quality standards and test reports must be confirmed when purchasing.

4. 6061 aluminum profile purchasing notes

• Confirm whether the profiles comply with international standards (such as ASTM B221, EN 755, GB/T 5237, AMS 4150)
• Ensure that the manufacturer has stable extrusion & processing capabilities (such as whether to use an extruder above 6000T)
• Focus on production tolerance & quality inspection (such as wall thickness uniformity, hardness testing, mechanical properties)
• Whether to provide secondary processing services (CNC cutting, welding, bending, anodizing, etc.)
• Logistics & delivery capabilities (whether global supply is supported, and whether the delivery time meets project requirements)

When purchasing 6061 aluminum profiles, you should consider strength, corrosion resistance, machinability and application requirements. Chalco has a global supply chain system, providing full-specification 6061 aluminum profiles, professional processing customization & surface treatment services to ensure that every customer can find the most suitable aluminum alloy solution.
