With a minimum of 10% chromium content, stainless steel is known for corrosion resistance. It's typically not as strong as steel and can be more difficult to machine.

A combination of high strength, hardness, and wear resistance makes tool steel especially well-suited for use as cutting tools.

Also known as chatter-free tungsten, this material is used for boring bars and grinding tools that dampen noise and vibration while machining.

This opaque and semi-clear plastic is often used in place of metal where a lightweight material is desired, such as for signs, equipment housings, and gears.

Stronger than Garolite CE with better electrical-insulating properties, Garolite XX is often fabricated into low-cost electrical components.

Garolite CE is often fabricated into parts where high strength is not required.

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.
