    Neodymium iron boron (NdFeb) magnets, also known as rare earth magnet and neo magnets, offer the best value when comparing performance, size and cost. Neodymium iron boron magnets, normally called neo and rare earth magnets, are moderate in price and typically allow for dimensional reductions. Neo magnets or rare earth magnets have poor resistance to corrosion and should have a coating or plating applied. Consideration should be given to the grade of alloy when exposing Neodymium iron boron ( neo and rare earth magnets ) to temperatures above ambient room. Neo ( rare earth and Neodymium iron boron ) magnets have good resistance to external demagnetization fields because of its high Intrinsic Coercive Force (Hci). This resistance makes Neodymium iron boron magnets an excellent choice for electromechanical applications.
    (NdFeb) Neodymium Iron Boron Magnets Manufacturing Process
    Fully dense Neodymium Iron Boron Magnets "neo magnets & rare earth magnets" are usually manufactured by a powdered metallurgical process. Micron size Neodymium and iron boron powder is produced in an inert gas atmosphere and then compacted in a rigid steel mold or in a rubber mold. The rubber mold is compacted on all sides by fluid and it is referred to as isostatic pressing. The steel molds will produce shapes similar to the final product, while the rubber mold will only create large blocks (loaves) of Neodymium iron boron "commonly known as neo or rare earth" magnet alloy. The Neodymium iron boron alloys magnetic performance in both compacting methods is optimized by applying a magnetic field before or during the pressing operation. This applied field imparts a preferred direction of magnetization, or orientation to the Neodymium Iron Boron Magnet alloy. The alignment of particles results in an anisotropic alloy and vastly improves the residual induction (Br) and other magnetic characteristics of the finished rare earth magnet named Neodymium Iron Boron magnet which is also called "neo magnet". After pressing, the neo "Neodymium Iron Boron" magnets are sintered and heat treated until they reach their fully dense condition. The die pressed neo / rare earth magnets are ground to the final dimensions, but the brick magnets from the rubber mold method are usually squared on large grinders and then sliced to the final geometry. Isostaticly pressed alloy has higher magnetic properties than the die pressed material, but it may lack the uniformity. The choice of Neodymium iron boron "rare earth / neo" magnet manufacturing method is usually application driven and is typically not a concern of the customer.
    (NdFeb) Neodymium Iron Boron Magnets Temperature Characteristics
    Sintered Neodymium Iron Boron "neo / rare earth" magnets are susceptible to demagnetization when exposed to elevated temperatures. There are many grades which can withstand high temperatures, but several factors will dictate the performance of the Neodymium Iron Boron magnet. One of the most pertinent variables is the geometry of the neo / rare earth magnet or magnetic circuit. Neo / rare earth magnets which are thin relative to their pole cross-section (Magnetic Length / Pole Area) will demagnetize easier than neo magnets which are thick. Magnetic geometries utilizing backing plates, yokes, or return path structures will respond better to increased temperatures. The maximum recommended operating temperatures listed on the Neodymium iron boron magnet magnetic characteristics page does not take into account all geometry conditions. Please contact us for Neodymium magnets design assistance when elevated temperatures are involved in your application.
