About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Tight-Tolerance Easy-to-Machine 303 Stainless Steel

This material has tighter tolerances than standard 303 stainless steel. Widely used for fabricating fittings and fasteners, 303 stainless steel machines quickly without sticking to cutting tools. It maintains its corrosion resistance in temperatures up to 1500° F.

Bars have close tolerances on the thickness and the width.

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.
