Tight-Tolerance Multipurpose 6061 Aluminum Sheets and Bars
- Yield Strength: 35,000 psi
- Hardness: Brinell 95 (Soft)
- Temper: See table
- Fabrication: See table
- Specifications Met: ASTM B209
These sheets and bars are precision ground either on all six sides or just on the top and bottom. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.
Sheets and bars that are precision ground on all sides are consistently flat, square, and parallel on all six sides. They’re also known as blanks and are ready for use in your CNC machine.

Multipurpose 6061 Aluminum Sheets and Bars
The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.
Extruded sheets and bars are formed by a die for close-tolerance widths, then cut to the lengths listed.
Aluminum that meets ASTM B209 or ASTM B221 complies with standards for materials.
Aluminum that meets an SAE AMS standard conforms to the material and process needs of the aerospace industry.
