N52 Industry Rare Earth Neodymium Magnet Permanent Thin Ring Magnets
Neodymium Iron Boron (NdFeB) Magnets
Neodymium Iron Boron magnets are a type of rare earth alloy that typically has two atoms of Neodymium (Nd), 14 atoms of Iron (Fe), and one atom of Boron (B) as its primary elements, hence their chemical composition Nd2Fe14B, which is commonly abbreviated as NdFeB. There are other elements that are used to increase the coercivity, to gain lower oxidation characteristics, and to obtain other desirable characteristics. These elements are used to "dope" the alloy and are generally found in small quantities (<10% by weight).
Sintered Neodymium Iron Boron Magnets
The sintered Neodymium Iron Boron magnet is produced by the OPS (orient-press-sinter) method. A crystalline alloy of Neodymium, Iron, and Boron is ground to a sub-micron powder using a ball mill, then aligned in a strong magnetic field, and pressed into a basic shape. The resultant "block" is then sintered, thereby fusing the material into a solid metal.
Key Advantages of Neodymium Magnet
Neodymium Magnet are the most powerful commercially produced magnets.
Neodymium Magnet have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
Neodymium Magnet can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
Neodymium Magnet has very high strength.
Relatively low cost.
Compared to Alnico and SmCo magnets, relatively easy to machine
