           1. What Are Aluminum rectangular tubes?

An aluminum rectangular tube is a hollow aluminum profile with a rectangular cross-section, characterized by high structural strength, light weight, and a neat, aesthetically pleasing appearance. Its rectangular cross-sectional design provides excellent performance under bi-directional bending while facilitating connection and assembly.

Common Classifications:

• Standard Rectangular Tubes (uniform wall thickness)
• Special-Shaped Rectangular Tubes (non-uniform wall thickness, reinforced rib design)
• Large-Section Rectangular Tubes (for curtain wall structures)
• Precision Rectangular Tubes (requiring high dimensional tolerances)

YouHeng’s Professional Advantages:

           3. Why Choose 6061 Alloy First? What Other Materials Are Available

Why Is 6061 Commonly Used?

6061 aluminum alloy is one of the most commonly used materials for aluminum rectangular tube, offering the following advantages:

• Excellent overall mechanical properties: tensile strength can exceed 290 MPa
• Superior machinability: easy to cut, drill, mill, and perform other machining operations
• Good weldability: compatible with TIG, MIG, and other welding methods
• Excellent corrosion resistance: particularly suitable for outdoor applications
• Good anodizing performance: capable of achieving high-quality oxide films
• Youheng provides various heat treatment conditions such as T6 and T651

  

Other Available Materials:

Series Pure Aluminum (e.g., 1050, 1060, 1100):

• Purity exceeding 99%
• Excellent electrical and thermal conductivity
• High corrosion resistance and plasticity
• Relatively lower strength
• Suitable for conductive parts, chemical containers, etc.

Series Corrosion-Resistant Aluminum (e.g., 3003, 3004, 3105):

• Manganese addition improves strength
• Better corrosion resistance than pure aluminum
• Good formability
• Suitable for cookware, tanks, architectural decoration, etc.
