Neodymium ring magnets are a combination of Neodymium (Nd), Iron (Fe) and Boron (B), and are also referred to as NdFeB or Neo. These are the strongest of the rare earth magnets and used in virtually every industry. Due to their high magnetic strength, neodymium ring magnets have replaced other magnetic materials in order to make a design smaller while achieving the same result.
We producing neodymium ring magnets in different lengths, OD/ ID diameters, finishes and premium grades. Finishing options for NdFeB ring magnets are uncoated, with a triple- coating (Ni-Cu-Ni) nickel finish or coated with Aluminum IVD (Ion Vapor Deposition) for optimal corrosion resistance.
Ring magnets are used as Electric Motor Magnets, as a Ring Magnet levitation display, Bearing Magnets, in high-end speakers, for Magnetics Experiments & magnetic jewelry.
Ring Magnet grades include N42, N45, N48, N50, & N52, The residual flux density ranges of these ring magnets run from 13,500 to 14,400 Gauss or 1.35 to 1.44 Tesla.
Neodymium Ring Magnet Pull force ranges in this catergory run from 1 lb to 400 lbs
Depending on the application, you may need a Neodymium Ring Magnet, or a disc magnet with a hole in it. Although the hole can be placed at nearly any position on the disc, the hole is almost always centrally located. The Ring Magnet is used for fitting the magnet to another item, for example as part of an assembly. Particularly large Ring Magnets can also be used to make use of the parallel magnetic field within the aperture of the ring.
Ring Magnets are magnetized through the height or thickness, not the diameter. This makes the ring magnets attractive to use in removing metal particles from tanks and reservoirs. A ring magnet can be slid over a post to collect unwanted metal filings or chips.
Neo ring magnets are being designed into a new generation of motors, generators, hydraulic cylinders, pumps & sensors. They also remain popular in high-end loudspeakers & high-intensity separators.
