          1. What Are Aluminum Flat Bars?

Aluminum flat bars are aluminum or aluminum alloy products with a rectangular cross-section, typically wider than they are thick, featuring flat surfaces and precise dimensional tolerances. Depending on the production process, they can be categorized into two types: hot-rolled aluminum flat bars and cold-rolled aluminum flat bars.

Hot-rolled aluminum flat bars:

• Produced through high-temperature rolling processes
• Relatively rough surface and lower dimensional accuracy
• Suitable for structural components with less stringent surface requirements
• Typical thickness range: 3–150 mm; width range: 20–600 mm

Cold-rolled aluminum flat bars:

• Rolled at room temperature
• Smooth surface and high dimensional accuracy
• Suitable for precision-machined components
• Typical thickness range: 0.2–6 mm; width range: 20–300 mm

  

Youheng’s Professional Advantages:

• Complete hot-rolling and cold-rolling production lines
• Capability to provide aluminum flat bars with special alloy formulations
• Support for non-standard size customization with flexible minimum order quantities
• Provision of material performance test reports and chemical composition analysis

          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 flat bars, 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.
