Product Description
Nd-Fe-B permanent magnet with its excellent performance, abundant raw material and reasonable price is to be rapid development and wide application.

demagnazation curve for 33EH grade in difference temperature:
The NdFeB magnet 's advantage is 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.
The disc magnets used in instrumentation,electro-acoustic motor,magnetic magnetization device,micro motors,electronic industry,automobile industry,petrochemicals,nuclear magnetic resonance device,etc
The NdFeB magnet EH grade's properties as follow:
