NdFeB permanent magnet with its excellent performance, abundant raw material and reasonable price is to be rapid development and wide application.
Also becoming increasingly popular across a wide range of novelty products for markets.
APPLICATION:
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,

The advantage of NdFeB magnetis high cost-effective, with good mechanical properties, easy cutting; according customer's demand to manufacture in a wide range of shapes, sizes and grades.
Also have high Br,high Hcj,high (BH)max,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.
