Zinc-platedsteel is stronger and more durable than other metals. It has fair corrosion resistance, so it should be used primarily in dry environments. Aluminum is lighter in weight than other metals and has good corrosion resistance. 303stainlesssteel has very good corrosion resistance, so it’s the best choice for high-humidity environments.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
