Rare earth magnets is one kind of the permanent magnets. Material Grade of NdFeB magnets as follow
1.Magnet N-( N35, N38, N40, N42, N45, N48, N50),
2.Magnet M-(35M, 38M, 40M, 42M, 45M, 48M),
3.Magnet H-(35H, 38H, 40H, 42H, 45H),
4.Magnet SH-(30SH, 33SH, 35SH, 38SH, 40SH, 42SH),
5.Magnet UH-( 28UH, 30UH, 33UH, 35UH, 38UH),
6.Magnet EH-(28EH, 30EH, 30EH, 33EH, 35EH)
Rare earth magnets' applications:
1) Application of NdFeB magnet:Toys, package, Printer, Switchboard, Phone, voice coil motors (VCM's) in hard disk drives, high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors, loudspeakers etc.
2) The coating of NdFeB magnets can be Zn, Ni, Ni-Cu-Ni, Epoxy, CR3+ZN, NI+AG, NI+AU.
3) Our factory can also manufacture various sizes of NdFeB magnet, according to the customer's specification
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.
