Golden Supplier Customized Radial Oriented Sintered Strong Large N52 Rare Earth Ndfeb Toroidal Neodymium Magnet Ring
China has the most complete industrial chain of rare earth permanent magnet in the world and has become the largest export base of rare earth permanent magnet materials.The demand for rare earth permanent magnet materials in the world is increasing day by day in the main countries. With the rapid development of the low-carbon energy-saving manufacturing industry represented by new energy vehicles and wind power generation, the global demand for high-performance Ndfeb permanent magnet materials is expected to enter the period of rapid development.
Grades of Neodymium Magnet
Neodymium( NdFeB )magnets are the type of rare earth magnet
commercially available and are manufactured in a wide range of
shapes,sizes and grades. Neodymium magnets are all graded by the
material they are made of. As a very general rule, the higher the
grade (the number
following the 'N'), the stronger the magnet. The highest grade of
neodymium magnet currently available is N52. Any letter
following the grade refers to the temperature rating of the magnet.
If there are no letters following the grade, then the magnet
is standard temperature neodymium. The temperature ratings are
standard (no designation) - M - H - SH - UH - EH.
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.
