Neodymium Magnets Features & Characteristics
- Grades & Materials - We carry a large inventory of licensed, neodymium magnet materials in both standard and premium grades for reduced production and lead times. We offer sintered neodymium magnets in grades ranging from N33 to N53. Visit our neodymium magnet materials page for additional information and for data sheets about this material.
- Sizes & Shapes - Sizes for standard Neodymium Iron Boron rare-earth magnets range from a few millimeters to approximately 150 mm, while assemblies can weigh up to several tons. Standard shapes that we carry include discs, blocks, rings, and arc segments in various sizes and grades. Non-standard shapes and sizes can be custom fabricated to your exact specifications from raw stock.
- Temperature Considerations - Neodymium magnets are temperature sensitive. For applications in which the magnet may be exposed to temperatures in excess of about 250°F (120°C), careful consideration must be given to the choice of magnet grade and the magnetic circuit. Send us a request for quote or contact us today and our experienced team of engineers can help you to determine the best and most cost-effective choice for your project.
- Manufacturing Methods - Due to the relatively brittle nature and high-magnetic strength of NdFeB magnets, cutting and grinding should be done prior to magnetization. We are fully equipped to machine these materials to virtually any shape and size for your project’s specialty requirements using our in-house grinding and EDM facilities. Finishing to tolerances of +0.0001” can be achieved, as required.
- Surface Treatment - Neodymium magnets are susceptible to oxidation, so painting or plating is highly recommended to prevent corrosion. The surface treatments we offer include nickel plating, zinc plating or epoxy coating.
- Magnetizing & Assembly Considerations - Neodymium rare-earth magnets are anisotropic and have a strongly preferred magnetic orientation. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. Magnetizing fields in excess of 35 kilo Oersteds are required to magnetize these materials.
- Handling & Storage - Neodymium materials are relatively brittle, but are magnetically very strong. They must therefore be handled carefully to avoid injury to personnel and damage to the magnets.
Neodymium iron boron magnets (also known as NdFeB magnets) are the most powerful type of permanent magnets commercially available today, with magnetic properties that far exceed alnico magnet and ferrite magnet materials. Sintered neodymium magnets offer extremely high energy product for their compact size, they have a high-magnetic remanence and much higher coercivity than other permanent magnets.. They are also relatively low-cost and available in a wide range of shapes, sizes and grades.
