6061 Aluminum - High Chromium Aluminum

Alro stocks 6061 aluminum. This grade of aluminum is one of the first to be developed in the early 20th century and 6061 aluminum remains among the most popular to this day. Due to the high chromium content of 6061 it is very resistant to corrosion. It is typically used in application that require welding or brazing.

Working with 6061 Aluminum

In temper 0 6061 has excellent formability and it is good in T-4. Machining can prove more challenging than with other machining alloys; it is particularly gummy in 0 condition, and fair in harder tempers. This is oftened outweighed by the excellent corrosion resistance and appearance after anodizing which is the highest of screw machine alloys, though properties are generally lower.

Alro stocks 6061 aluminum tubing, pipes, plates, and sheets, in a variety of shapes.

Comparing Aluminum Grades

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 have differing composition ratios that 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

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.

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.

General Characterisitcs of 6061 Aluminum

  • Very high corrosion resistance
  • Excellent formability at temper 0
  • Good formability at grades above 0
  • Machining at temper 0 can be 'gummy'
  • Machining at grades above 0 is fair
Typical Uses

6061 aluminum is extremely versatile and suitable for small and large components alike. This has made it one of the most commonly used aluminum alloys. Typical applications include:

  • Railway car components
  • Yachts, boats, and aircraft structures
  • SCUBA tanks
  • Bridge components
  • Pipe fittings
  • Wheels and various transportation end uses
  • Food and beverage cans
