- Aluminum resists corrosion and tarnishing and is lightweight.
- Aluminum 3003 has been alloyed with manganese and can be work-hardened.
- Aluminum 6061 has been alloyed with magnesium and silicon. It has good strength, resists stress cracking and corrosion, and exhibits good weldability. It is one of the most common alloys of aluminum for general purpose use.
- Brass resists corrosion and is nonmagnetic. It polishes to a rich, golden color and is often used decoratively.
- Brass 260 is lower strength than Brass 330, but also elongates less.
- Brass 330 has a lower lead content than other brass alloys and has excellent cold workability.
- Bronze resists corrosion caused by brine, gasses, and sulfite solutions. It is nonmagnetic and nonsparking, with a smooth finish.
- Carbon steel 1010 tubing is made from plain carbon steel with nominal 0.10% carbon content.
