Product Description

General Introduction:
1. Our NdFeB rare earth magnet is particularly suitable for high volumn production of a wide variety of shapes and size ranges
2. Precise dimensional control is achieved in both processed and usually the component does not require further machining
3. Injection moulded NdFeB do not normally require coating due to better corrosion resistance, however coating is recommended for compression moulded NdFeB
 
Features
1. High energy ranging from 8MGOe to 48MGOe with wondrerful coercive force
2. Less expensive,and mechanically stronger and less brittle than SmCo
3. Density:13%,smaller than SmCo products
4. For most applications,coating or plating is recommended...

 
Advantages:
1. High energy
2. Very high Hc and Hci output
3. More economical than SmCo
4. Wonderful performance at ambient temperature
