Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Brass—Resist corrosion in wet environments. Brass is softer and less likely to dent surfaces than steel. Don't mount brass standoffs directly to steel, or they'll create a short circuit that reduces magnetism up to 15%.

Alnico Magnet—Retain their magnetic strength, even when exposed to high temperatures.

Neodymium Magnet—Our strongest magnets. These support heavy connections, but have lower heat resistance than Alnico magnets.
