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

Easy-to-Machine Gray Cast Iron Sheets and Bars
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A247
Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often fabricated into gears, pulleys, and bushings.

Wear-Resistant Easy-to-Machine Delrin® Acetal Resin Sheets, Bars, and Strips
These sheets, bars, and strips resist expanding when exposed to heat and moisture, so they can be easily machined to close tolerances. They also have a naturally slippery, wear-resistant surface. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.
White sheets, bars, and strips are FDA compliant for contact with food.
