Factory Wholesale Stainless Steel N52 Ring Magnet Neodymium
In the field of information technology, neodymium magnets are
particularly used in hard disc drives, mobile phones, video and
audio systems of television [1]. Neodymium magnets are also
commonly used in magnetic separators, filters, ionizers, in
production of on–off buttons, safety sector and security systems.

Platings/Coatings
Neodymium magnets are a composition of mostly Neodymium, Iron and
Boron. If left exposed to the elements, the iron in the magnet
will rust. To protect the magnet from corrosion and to strengthen
the brittle magnet material, it is usually preferable for the
magnet to be coated. There are a variety of options for coatings,
but nickel is the most common and usually preferred. Our nickel
plated magnets are actually triple plated with layers of nickel,
copper, and nickel again. This triple coating makes our magnets
much more durable than the more common single nickel plated
magnets. Some other options for coating are zinc, tin, copper,
epoxy,
silver and gold. Our gold plated magnets are actually quadruple
plated with nickel, copper, nickel and a top coating of gold.
Common direction of magnetization
1> Disc, cylinder and Ring shape magnet can be magnetized
Axially or Diametrically.
2> Rectangle shape magnets can be magnetized through Thickness,
Length or Width.
3> Arc shape magnets can be magnetized Diametrically, through
Width or Thickness.
