NdFeB magnet is easy to rust, oxidation, so the Sintered NdFeB's surface is usually required for plating such as zinc, nickel, silver, gold, etc.

Sintered NdFeB Magnets have a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.

The 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.

Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.The magnet material is currently the strongest type of permanent magnet in the world.

Pic shows the Sintered NdFeB Magnet block with NiCuNi coating,the magnetized direction is through the thickness.
