Product Introduction
Neodymium Iron Boron (NdFeB) is the most powerful permanent magnet materials today. Sintered NdFeB magnets are available in a number of different grades that span a wide range of properties and application requirements. For details, please see the following table.
This kinds of magnets are brittle, and machining operations should be performed prior to magnetization, using diamond tools. We are equipped to fabricate these materials to blueprint specifications.
Almost all Sintered NdFeB magnets are an-isotropic, and can only be magnetized in the orientation direction. In general, magnetizing fields of about 30 KOe are required to saturate NdFeB magnets, with high coercivity grades requiring about 40 KOe.
Application
- Motors
- Medical devices
- Loudspeakers
- Toys
- Magnetic separation devices
- Magnetic Systems
