demagnetization curve for neo magnet thin section:
neo magnet thin section has a very high energy product and coercivity,
also have high Br,high Hcj and high stability become the important material of the world.
The shortcoming is the low of the Curie temperature and the temperature characteristics, easy to rust, oxidation, Sintered NdFeB's surface is usually required for plating such as zinc, nickel, silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.
This neo magnet thin section is coated black Ni.
This neo magnet thin section is coated black Ni.
The application for neo magnet is very widely:
instrumentation,
electro-acoustic motor,
magnetic magnetization device
micro motors,
electronic industry,
automobile industry,
petrochemicals,
nuclear magnetic resonance device,
sound device magnetic suspension system,
magnetic transmission machine
magneto therapy equipment
high performance motors,
brushless DC motors,
generators,
magnetic separation,
