This material has tighter tolerances than standard 303 stainless steel.

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

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.

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.

Substitute 7050 aluminum for 7075 in structural applications when high stress-corrosion resistance is required. It is the same material that's used for bulkheads and fuselage frames.

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Sometimes called flat stock, these bars have a thickness and width that are precision ground to a tight tolerance.

A lead-free alternative to 12L14, 1215 carbon steel contains the same amount of sulfur and phosphorus for excellent machinability. It’s often used for jigs and fixtures.

With the highest lead content of all the brass alloys, 360 offers the best machinability. Often called free-machining and free-cutting brass, it stands up to high-speed drilling, milling, and tapping operations with minimal wear on your tools. It’s commonly used for gears, pinions, and lock components.

Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

Add stiffness to composite sandwiches without adding a lot of weight.
