Properties
6061 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
Typical Uses
  • Railway car components
  • Bridge components
  • Pipe fittings
  • Wheels and various transportation end uses

6061 Extruded Structural Tube

Alro stocks 6061 extruded structural aluminum tube.  6061 is one of the first aluminum grades developed in the early 20th century, which still remains among the most popular to this day. 6061 aluminum is generally selected where welding or brazing is required, or for its particularly high corrosion resistance in all tempers, due to its noteworthy chromium content.

Alro stocks 6061 drawn seamless in a round tube shape.

7075 Aluminum vs. 6061 Aluminum

Because they both contain largely the same alloys, 7075 and 6061 aluminum are often cross-compared as grade options for any given application. But the two aluminum grades’ differing composition ratios make them respectively suitable for different types of production needs.

7075 aluminum contains more zinc than 6061. This makes it more corrosion resistant and strong, but less easily shaped than 6061, which is more malleable, weldable, and versatile. As a result, 7075 is preferable for high stress applications like aerospace or military equipment, while 6061 is useful for crafting particularly shaped parts that face less strenuous wear, like transit infrastructure, stairs, or small water vessels. Analyze the pressures of your project's use environment to make the right aluminum grade choice.

6063 Aluminum vs. 6061 Aluminum

Likewise, 6061 aluminum often draws comparisons with 6063 aluminum, as both grades are commonly used to craft structural parts. While the two are extremely similar and often present negligible differences in application, 6061 provides a notably higher yield strength for parts that need to withstand exceptional force. Regardless of your choice, 6061 or 6063 aluminum will provide your project with high weldability and formability.
