A neodymium magnetic (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the ND2Fe14B tetragonal crystalline structure.
Neodymium magnets are the strongest type of permanent magnet made. They have replaced other types of magnet in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.
Magnetic property of Neodymium Rare Earth Magnet
Neodymium magnets 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, Neodymium 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.
Armstrong Magnetics N40 Neodymium magnets in disk and rectangle shapes for customers' immediate needs and accept special orders for custom Neodymium magnets.
Neodymium magnets are most powerful of any kind of magnetic materials
Br of Neodymium magnets are much more than 11, 000 Gauss. Therefore, Neodymium magnets have strong holding strength on metal surface and could be used as component for holding, separating, etc.
Neodymium magnets must be carefully handled to avoid personal injury and material damage due to its extremely magnetic strength and brittle property.
Neodymium magnets are sensitive to temperature change and even lose magnet properties at high temperature
Neodymium magnets lose -0.09 ~ -0.13% of Br/° C and can work stably under 80° C for low Hci Neodymium magnets and 150° C for high Hci Neodymium magnets.
Neodymium magnets are corrupted in humid environment
Surface protection is strongly recommended, such as plating, varnishing and encapsulating.
Neodymium magnets are hard and brittle
Neodymium magnets can be abrasively machined with coolant served to absorb heating and dust. Without coolant, rare earth magnets could crack and chip by the heat produced during high speed cutting or grinding, and the sparks contain the easily oxidized grinding dust that could cause fire!
Tolerance of Neodymium magnets
Unless otherwise specified, tolerance on dimension of magnetization is ± . 005". Other dimensions are± 1.5% or ± . 010", whichever is greater.
