Material

• Brass is corrosive resistant, ductile at high temperatures, and has a low magnetic permeability.
• Carbon steel is steel with a main alloying constituent of carbon.
• Cast iron is a strong, brittle, non-ductile, iron-carbon alloy.
• High-carbon steel is steel with a main alloying constituent of carbon. Compared to regular or low-carbon steel, high-carbon steel is harder and stronger, with a lower melting point.
• Nylon is very strong and flexible, has excellent abrasion resistance, is lightweight, and resists crushing and cracking.
• Polyoxymethylene (POM), sometimes called acetal, is a thermoplastic copolymer, characterized by its hardness, low coefficient of friction, and high resistance to heat and abrasion.
• Stainless steel resists scaling and corrosion.
• Steel is a good general-purpose material.
