Neodymium Magnet are composed of Neodymium, Iron and Boron. Density of Neodymium magnets is. 27Lb/in3 (7.5g/cm3).
Neodymium Magnet are manufactured in a metallurgy process through alloying, crushing, powdering, pressing w/magnetic orientation, sintering, then cutting, coating, inspecting and packing before shipment.
Neodymium Magnet offer the highest (BH)max and high Hci(BH)max, the Maximum Energy Product, of Neodymium magnets is highest of any kind of permanent magnets today in the world. (BH)max at different grades of Neodymium magnets is 27 to 52 MGOe. Neodymium magnets have extremely resistance to demagnetization with Hci, Intrisic coercive force, over 12, 000 Oe. Because of very high (BH)max and Hci, Neo magnets could be used as a reversible medium for large amount of energy transformation in miniaturized application where a strong magnetic demagnetization field exists, such as computer hard drive. Disk and rectangle shapes for customers’ immediate needs and accept special orders for custom Neodymium magnets.
Flat but strong disc magnet. Suitable for the construction of magnetic key boards for example. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets. For more information please click here: facts about magnetism; safety precautions. NdFeB Disc Magnets N45 Nickel
