Zinc-plated steel extensions are corrosion resistant in wet environments. They are also magnetic.

All 18-8 stainless steel extensions have good chemical and corrosion resistance. They may be mildly magnetic. Black-oxide 18-8 stainless steel extensions have a matte-black finish.

316 stainless steel extensions have excellent chemical and corrosion resistance, can be used in saltwater environments, and may be mildly magnetic.

All aluminum extensions are lightweight, corrosion resistant in wet environments, electrically conductive, and nonmagnetic. Black-oxide aluminum extensions have a matte-black finish.

Brass extensions are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They’re also friction resistant, so you can make smooth adjustments when they’re used as pivot points.
