Permanent rare earth neodymium ring industrial magnet

Neodymium Iron Boron (NdFeB) magnet has high remanence, high coercive force, high energy product and high performance/cost ratio. It is easily formed into various sizes, widely used in motor, sensor, meter, sound device, magnetic separator, automobile, aviation, aerospace and other applications. It is prone to corrosion in humid environments, so it usually needs surface treatment according to customers' requirements. The coatings we can offer include: nickel, zinc, gold, silver, epoxy and parylene.

Material grade: N35, N38, N40, N42, N45, N48, N50, N52. 
Production chart: Raw material---Mixing---Vacuum melting---Powder production---Molding---Vacuum sintering---Testing---Cutting and Grinding---Surface coating---Inspection---Packing---Shipping
Coating: Zinc, Nickel, Aurum, Silver, Epoxy, Phosphating, Parylene.
Shape: Disc, Ring, Block, segment, Cylinder, Trapezoid, Customized design(Design proper magnets for clients specific requirements)
Typical Magnetic Properties:
N35, N38, N42, N38SH...what does it all mean? 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.
