Nylon

Nylon is a versatile low-cost plastic, ideal for parts that require high compressive strength and friction resistance, while machining to very tight tolerances. It can be used in place of metal in some applications, allowing for longer-wearing parts that require lower maintenance than its metal counterpart. Nylon generally is stronger, withstands higher temperatures, and is more cost efficient than PTFE, PEEK, and UHMW.

Nylon has a machining cost factor of 0.8 when compared to steel 12L14.
