Product Description Neodymium Magnets, also known as NdFeB, NIB, or Neo magnets, are the most widely-used type of rare-earth magnets. Neodymium Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). It is the strongest type of magnet and manufactured in a wide range of shapes, sizes, and grades and different coatings/finishes. Place of OriginXiamen, China(Mainland)Magnet TypeSintered NeFeB / rare earth / PermanentCompositeNeodymium-Iron-BoronGradeN35-N54( M, H, SH, UH, EH, AH series )Working TemperatureThe Max. temp. is up to 80 / 100 /120 /150 / 230 celsius under different grade.Tolerance+/-0.03 to +/-0.15Shape of MagnetDisc, Cylinder, Block, Ring, Sphere(ball), Arc Segment(Tile) and more custom shapesSizevarious sizes custom-make welcomeCoatingNi, Zn, NiCuNi, gold, silver, copper, epoxy, etc.Magnetization DirectionAxially Magnetized, Radially Magnetized(Diametrically), Multi-poles Magnetized or other customizedCertificateISO9001:2000,QS-9000:1998,SGS,RoHS,REACHApplicationIndustrial Magnet, Toy Magnet, Health Magnet and more PackagingAntimagnetic Packaging / Neutral Packing / Custom-make welcomeShipping MethodAll shipping methods on offer.courier(TNT, DHL, FedEx, UPS), air or sea, with transit tracking regardless.Lead Time10~25daysMagnet DisplayNeodymium-Iron-Boron (NdFeB) magnets are composed of neodymium, iron, boron, and a few transition metals. These kinds of permanent magnets are extremely strong and can be produced in different shapes and sizes (ie. arcs, blocks, discs, rings).It has higher unit magnetic properties than other magnet and assures you of smaller size and lighter weight in designing devices.Grade cover N35-N52, N30M-N50M, N30H-N48H, N30SH-N45SH, N28UH-N40UH, N28EH-N38EH.
