1) high cost-effective,
2) good mechanical properties,
3) easy cutting;
4) make any size accroding customer's demand

NdFeB material is currently the strongest type of permanent magnet in the world.

Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.

NdFeB block magnet has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.

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.

Nd-Fe-B block 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.
