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.

Cold-rolled foil, sheets, and bars are cut from large pieces to the widths and lengths listed, so the edges may not be parallel.

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.

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.

Yield Strength: 20,000 psi
Temper: H32 (1/4 Hard)
Fabrication: Cold Rolled
Specifications Met: ASTM B209

One side of these sheets and bars is polished to either a brushed finish or a mirror-like finish. The polished side is covered with a protective, peel-off film. Known for being one of the easiest types of aluminum to weld, 5052 is also recognized for its ability to resist salt water. It's widely used for the bodies of boats, buses, trucks, and trailers, as well as for chemical drums.

Brushed sheets and bars are polished to a #4 satin finish with grain lines running in one direction to mask fingerprints.

Mirror-like sheets and bars are polished to a #8 reflective finish and are free of grain lines.

Easy-to-Form Pure 1000 Series Aluminum Sheets and Bars

Made of 1000 series aluminum which is 99% pure, this aluminum offers superior formability, corrosion resistance, and electrical conductivity. It's frequently fabricated into raceways, decorative trim, and other parts where strength and hardness are not required. These temper O foil, sheets, and bars are annealed to the softest state possible, which is sometimes called “dead soft.”

High-Strength 2024 Aluminum Sheets and Bars

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Cold-rolled sheets are cut from large pieces to the widths and lengths listed, so the edges may not be parallel.

High-Strength 7075 Aluminum Sheets and Bars

Originally developed for aircraft frames, uses for 7075 aluminum now include keys, gears, and other high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

Hot-rolled, cold-rolled, and cast sheets are cut from large pieces to the widths and lengths listed, so the edges may not be parallel.
