Notes
- Brass is an alloy of zinc and copper.
- Bronze is an alloy of copper and tin, sometimes other metals are included.
- Ferrous metal is any metal with iron as a primary ingredient. Examples of ferrous metals include iron, tool steel, stainless steel and high nickel or cobalt alloy steels.
- Hastelloy is a high temperature, nickel-based alloy metal.
- Inconel is a high temperature nickel and chromium alloy metal.
- Monel is a copper-nickel alloy with a small amount of iron and cobalt. It is non-corrosive and used to make chemical equipment and food processing equipment etc.
- Non-ferrous metals are usually somewhat "gummy" and belt speed may need to be slowed or a lubricant may need to be used. Examples of non-ferrous metals include aluminum, zinc, brass, bronze, copper, magnesium, titanium and zirconium.
- Pewter is an alloy of tin, copper, and lead. It is a non-ferrous metal.
- There are 2 types of plastic:
- Thermosetting plastics do not soften with heat, such as epoxies, phenolics, polyesters, polycarbonates, melamine, "CORAIN" by Dupont and similar countertop materials like Nevamar, Fountainhead, Avonite, Formica 2000X.
- Thermoplastics do soften with heat. Examples include Acrylics, Nylons, urethanes and Delrin.
- Polyester is used in the furniture industry to achieve a "wet look" or a highly polished finish.
- Stellite is a high temperature non-ferrous alloy containing cobalt, tungsten and chromium; used mostly in cutting tools for machining metal.
- Waspaloy is a high temperature metal alloy.
