NdFeB magnet:

Ndfeb magnet,the third generation of rare-earth permanent magnet,is the most powerful and advanced permanent magnet today.Ndfeb is named as “Magnet King”for its high remanence,high energy.Moreover,it has the high performance and high cost ration, because of the rich rare earth resources in China and the ever-changing production process and technological progress.It can be easily formed into various sizes and different shapes ,such as segment.ring,block and etc.

The process:

1.Preparation of raw materials

2.Melting & strip casting

3.Pulverizing and jet milling

4.Pressing immagnetic field

5.Sintering and aging

6.Machining

7.Coating

8.Magnetizing

9.Packing

Caution:

Neodymium magnets can be dangerous, as they generate extremely strong pull forces, therefore must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Neodymium magnets are brittle, and can shatter if allowed to slam together, launching small pieces at great speeds. Eye protection should be worn when handling there magnets.
