About Aluminum

Compare over 20 aluminum alloys to find the right material for you—all with material certificates for traceability.

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.

If you don’t see the sheet or bar size you need, please specify dimensions under additional sheet sizes or additional bar lengths.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

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 top and bottom are also known as flat stock.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
