Grade BN-6 Bonded Neodymium Magnets
Product Description:
Bonded Neodymium Magnets: Customized, Durable & Reliable
Bonded neodymium magnets, also known as bonded neo-magnets, are a
type of permanent magnet made with neodymium, iron, and boron. They
are manufactured using a pressing and sintering process and then
bonded with a composite material. Thanks to their high coercivity,
high remanence and low coercivity, bonded neodymium magnets are
highly reliable and durable. They are available in various shapes
such as disc, block, cylinder, ring, etc. and sizes that can be
customized according to your requirements. The maximum operating
temperature of these magnets is between 120°C-150°C and they can be
magnetized in axial, radial or multi-poles direction. Bonded
neodymium magnets are packed safely in carton boxes and pallets to
make sure they reach you in perfect condition.
