New Technology N52 Ndfeb Magnet

Choosing different coatings does not affect the magnetic strength or performance of 
the magnet, except for our Plastic and Rubber Coated Magnets.  The preferred coating
is dictated by preference or intended application.

♦ Nickel is the most common choice for plating neodymium magnets. It is actually a 
triple  plating of nickel-coppernickel. It has a shiny silver finish and has good resistance 
to corrosion in many applications. It is not waterproof.
♦ Black nickel has a shiny appearance in a charcoal or gunmetal color. A black dye is 
added to the final nickel plating process of the triple plating of nickelcopperblack nickel.
NOTE: It does not appear completely black like epoxy coatings. It is also still shiny, 
much like plain nickel plated magnets.
♦ Zinc has a dull gray/bluish finish, that is more susceptible to corrosion than nickel. 
Zinc can leave a black residue on hands and other items.
♦ Gold plating is applied over the top of standard nickel plating. Gold plated magnets 
have the same characteristics as nickel plated ones, but with a gold finish.

♦ Epoxy is basically a plastic coating that is more corrosion resistant as long as the 
coating is intact. It is easily scratched. From our experience, it is the least durable of 
the available coatings.
