1. What is Rare Earth Magnet
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and thenground or sliced into the desired shape. Coatings are then applied if required. Finally, the
blank magnets are magnetized by exposing them to a very powerful magnetic field in excess
of 30 KOe.
Grades :
Range: N35-N52; N35M-N50M; N35H-N48H, N35SH-N45SH; N30UH-N40UH, N30EH-N38EH
- The grade like N48-N52 could meet your requirements on strong power
- Standard one like N35 or N40 is okay for your normal applications
- Accept custom size and shape
