Traction Motors Neodymium Iron Boron Sintered Magnets
Product Description
Sintered Neodymium Magnet is a kind of rare earth magnet made of neodymium iron boron materials through sintering process. It is widely used in a variety of industrial applications due to its high coercivity and energy product. The magnetic orientation, certification, coating and grade can be customized according to customer requirement. It is certified by ISO9001, IATF16949, ISO14001, etc. The common coatings are nickel, NiCuNi, zinc, epoxy, etc. The grade is normally from N35-N52, 35M-50M, 35H-48H, 30SH-45SH, etc. It has the advantages of high magnetic strength, good temperature stability, good corrosion resistance, and low cost. Sintered Neodymium Magnet is widely used in the fields of industrial automation, automotive, medical equipment, motors, etc.

Packing and Shipping:
Sintered neodymium magnets are a special type of magnet that requires special packing and shipping in order to ensure its safe delivery. To ensure the safe and secure delivery of sintered neodymium magnets, we recommend the following process for packing and shipping:
- Magnet should be individually wrapped in a non-metallic material such as cloth or paper.
- The package should then be sealed in a protective package such as cardboard, plastic, or bubble wrap.
- The package should be labeled with a “FRAGILE” sticker.
- The package should be shipped using a reputable carrier that offers tracking services.
- The package should be insured in case of loss or damage.
