Product Description
Sintered Neodymium Magnet is a type of rare earth magnet made of Neodymium-Iron-Boron. It is also known as permanent magnet because the magnetism is "always on". It is widely used in new energy cars, wind power generation, servo motors, traction motors and other applications.
Sintered Neodymium Magnets come in various shapes, such as blocks, arcs, rings, and customized shapes. Coating options include nickel, NiCuNi, zinc, epoxy and other coatings. Magnetic orientation can be customized according to customer requirements. Various grades are available, ranging from N35-N52, 35M-50M, 35H-48H, 30SH-45SH, etc.

Packing and Shipping
Packaging and Shipping for Sintered Neodymium Magnet
Sintered neodymium magnet is a rare earth magnet which is very fragile and brittle. It must be packaged and shipped with special care.
Packaging
Sintered neodymium magnet should be individually wrapped in anti-static plastic with a foam padding between each piece to prevent accidental contact. Additionally, the product should be packed in sealed and shock-proof cartons to prevent any vibration or friction during shipping.
Shipping
Sintered neodymium magnet should be shipped by a reliable carrier that can ensure safe delivery to the customer. The parcel should be marked with a ‘Fragile’ label and be properly insured and tracked. Furthermore, the shipping rate should be reasonably calculated in order to avoid overcharging the customer.
