Hangseng Magnetech Inc. (SUPERMAG, neoi) is your best source for the highest quality magnets, neodymium magnets, magnetic devices and expert application assistance for OEM, point-of-purchase, industrial and retail markets.

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.

Huge Magnetic Ring for Speaker  Advantages of Sintered Neodymium Magnet

1. Thermostability
Magnetic properties of NdFeB deteriorate rapidly above about 130 Centigrade, depending on the grade of material, and the permeance coefficient of the magnet in operation. The higher the permeance coefficient the magnet operates at, the higher the temperature it will withstand. High Hci NdFeB materials operating at a high permeance coefficient can operate to about 210 Centigrade. Shapes, Sizes, and Grades Available Isotropic bonded NdFeB can be specially formulated to meet special requirements, with energy products from 1 to 10MGOe, as required.

2. Largest Magnetic Force
Br of Neodymium magnets are much more than 11,000 Gauss. Therefore, Neodymium magnets have strong holding strength on metal surface and could be used as component for holding, separating, etc.
Neodymium magnets must be carefully handled to avoid personal injury and material damage due to its extremely magnetic strength and brittle property.

3. Surface Treatment
Neodymium Magnets are sensitive to temperature change and even lose magnet properties. They are easily corrupted in humid environment.
Surface protection is strongly recommended, such as plating, varnishing and encapsulating.
