Brass — Non-magnetic and non-sparking, with good corrosion resistance and a gold finish. Softer than steel, so it's for light loads and decorative or electrical work.

18-8 Stainless Steel — The standard stainless for outdoor and wet environments: it won't rust, is non-magnetic in the annealed state, and costs less than 316. Not suited to salt water or harsh chemicals.

316 Stainless Steel — The most corrosion-resistant stainless we stock. Chosen for salt water, pool and chemical exposure, where 18-8 can pit over time.
