Wholesale Promotional Hard Neodymium Magnetic Ring
Product Description
Neodymium iron boron ( NdFeB) is a type of rare earth magnetic material.
NdFeB is the most advanced commercialized permanent magnet material available today.This material has similar
properties as the samarium cobalt except that it is more easily oxidized and generally doesn't have the same
temperature resistance.
However, NdFeB magnets have the highest energy products approaching 52MGOe and are mechanically stronger
than samarium cobalt magents. NdFeB material is more costly by weight than
ceramic or alnico but produces the highest amount of flux per unit of volume or mass amking it very economical
for many ap
1) Material: Neodymium iron boron permanent magnetic material, Permanent Magnet;
2) Magnetization: Straight magnetization, Skewed magnetization;
3) Shape: Ring ,Arc ,Block ,Bar ,Ball etc
4) Size: customized size
Technical Data Sheet
Neodymium permanent magnet material available in the early 1980s, is now widely used in motor (motor), speakers (speaker), toys (toys) and some electrical appliances (electron), and other products. Components for Nd2Fe14B. Have very high magnetic properties, the largest energy product (BHmax) higher than the ferrite (Ferrite) 10 times more. Its own mechanical properties is also very good, cutting different shapes and bored. High-performance products of the highest temperature of up to 200 degrees Celsius. Because of its material content easily lead to corrosion, according to different requirements of different surface coating. (Such as plating Zn, Ni, Au, Epoxy, etc.)
