Neodymium ring, small and golden, suitable to design jewelry (although not to be called ‘nickel-free’ the nickel coat is covered by the golden one). All rings can be fastened by a nail or screw through their middle hole – but becareful: Do not spoil coating. Neodymium magnets must not be rasped or sawed – if their coating is not intact they will corrode. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets.

Small Ring Magnet Material:
NdFeB magnet, Neodymium magnet is an alloy magnet made from Nd, Fe, B and other metal elements,
which has the high remanence, high coercive force,
high energy and high performance/cost ratio.
Applications of Neodymium Magnets: magnetic buttons, micro-special electric machinery, audio equipments, permanent-magnet instrumental meters, electronic industry, auto industry, nuclear magnetic resonance equipments, magnetic suspension system, magnetic transmission gears and magnet therapy equipment, aero generators, loudspeakers, magnetic separators, magnetic separators, copiers, synchrotrons, radiation sources, free electron lasers, nuclear industry.
Shape, Dimension and Surface Coating:
We can produce the Neodymium magnet in Block, Ring, Disc, Cylinder, Arc, and Irregular
shapes according to customers’ requests.
