The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust. Neodymium square & rectangle & block magnets are available in a wide range of grades, dimensions, and coatings. It can, however, be abrasively ground before being plated, but only with the use of liberal amounts of coolant. Neodymium magnets, also known as NdFeB or Neo magnets, are a type of rare earth permanent magnets which made from Neodymium, Boron, Iron, and other minor elements. Machining - Since Neodymium is prone to chipping and cracking, it does not lend itself to conventional machining methods. Please see our safety warnings page for more information. It is highly recommended that when constructing rare earth magnetic assemblies, they be magnetized after assembly. Magnets can chip if allowed to “jump” at an attracting object. Fingers can be severely pinched between attracting magnets. Therefore, it is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets. Magnetizing and Handling - Neodymium magnets are very brittle and very strong magnetically. Cracks are acceptable as long as they do not extend across more than 50% of the pole’s surface. These are made of Neodymium, incredibly powerful, in fact, so powerful that if you get two of them joined. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Collections: Incredibly strong (neodymium) magnets. 005”, whichever is greater.Īccording to International Magnetics Association (IMA) standards, visual imperfections such as hair-line cracks, porosity and minor chips are commonly found in sintered magnets. We support customize make low temperature and high-temperature resistant magnet assemblies. Including custom shaped neodymium magnets, custom rare earth magnets, etc. Tolerances - For as-pressed material, tolerance on the thickness (direction of magnetization) is +/–. Custom Neodymium Magnet As a 15 years neodymium supplier and neodymium manufacturer, we can custom neodymium. They are called “rare earth” magnets because the elements of neodymium are classified as such in the lanthanides section of the Periodic Table of the Elements. The material is then sintered, ground to dimension, magnetized and tested. Manufacturing - In general, the elements are melted together and milled into a powder that is dry-pressed to shape in the presence of a magnetic field. Not sure if neodymium is the best material for your application? Review the attribute and application chart for all of our magnetic materials. Extremely strong for their size, Neodymium (Nd-Fe-B) rare earth magnets are composed of neodymium, iron, boron and a few transition metals.
