- A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
- Brass is an alloy of copper and zinc often with additional elements such as lead or tin; it is characterized by good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.
- Bronze is an alloy of copper with other elements such as aluminum, silicon or tin (aluminum bronze, silicon bronze, tin bronze, etc.)
- A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity; copper tube and fittings are frequently used in plumbing applications.
- Steel - Carbon & Alloy
- Generic classification for general purpose carbon steel, mild steel or steel alloys containing additions of chrome, nickel, molybdenum, vanadium or other elements to alter hardenability characteristics, toughness, hardness, corrosion resistance and/or strength. "Black pipe" is typically made of carbon steel.
- Steel - Stainless
- Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings; this selection includes all grades of stainless steel.
- Includes all grades of thermoplastic materials, such as ABS, nylon, fluoropolymers, etc.
