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

Among the strongest plastic materials we offer, Torlon PAI has a slippery surface that resists wear. Use it to make high-friction compressor parts, bearings, and seals.

This material has tighter tolerances than standard 304 stainless steel.

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. These balls are often used in bearings.
