What Is 6061 Aluminum?

6061 aluminum is one of the most commonly used aluminum alloys across a wide range of industries. Known for its excellent strength, corrosion resistance, and versatility, it is a go-to material for engineers, builders, and manufacturers around the world. In this article, we will explore what 6061 aluminum is, its composition, key properties, applications, and why it remains a top choice for both structural and mechanical uses.

As a trusted aluminum supplier, sasaaluminum provides high-quality 6061 aluminum in various forms to meet your project demands, from precision tubing to large structural plates.

Composition of 6061 Aluminum

6061 is a heat-treatable aluminum alloy primarily composed of:

  • Aluminum (Al) – base metal

  • Magnesium (Mg) – 0.8% to 1.2%

  • Silicon (Si) – 0.4% to 0.8%

  • Trace amounts of iron, copper, chromium, zinc, and titanium

The combination of magnesium and silicon makes 6061 part of the 6000 series, known for medium to high strength and excellent corrosion resistance.

Key Properties of 6061 Aluminum

6061 aluminum stands out due to its balanced mechanical and physical properties. Some of its most valued characteristics include:

  • Good strength-to-weight ratio

  • Excellent corrosion resistance, even in marine environments

  • High machinability for CNC and manual processing

  • Good weldability with proper techniques

  • Anodizing capability for improved surface protection and appearance

  • Thermal conductivity and electrical resistivity suitable for heat exchangers and electronic housings

6061 aluminum is often available in multiple tempers, such as 6061-T6 (solution heat-treated and artificially aged) and 6061-T651 (stress-relieved), which further enhance strength and stability.

Common Forms of 6061 Aluminum

At sasaaluminum, we provide 6061 in a wide range of product forms to meet the demands of different industries, including:

Each form is available in various sizes and finishes to fit your specific application.
