Permanent Magnets

Understanding permanent magnets / rare earth magnets and how their application can play into the innovative devices of today’s markets is the foundation of our business. Hangseng Magnetic Technologies’ long history of magnetic expertise – including supporting all patent, trademark and license requirements of magnets – allow us to partner with you to deliver the permanent magnet product for your needs.

HangSeng Magnetic Technology ship these permanent magnets magnetized or non-magnetize according to customers’ requests. Permanent magnets have high coercive force and therefore keep their magnetic field stably under a proper application after they are magnetized.

The term permanent magnet comes from the ability of the magnet to hold an induced magnetic charge after it is removed from the magnetizing device.

When to chose permanent magnets for your application? 

If you need help determining the best choice for your application, whether it be Neodymium Iron Boron MagnetsFerrite MagnetsAlNiCo Magnets or Samarium Cobalt Magnets, we would be glad to assist you. Simply give us a call at 86-574-27667267 or Email:info@hsmagnets.com.
