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.
The selection of Neodymium Iron Boron magnets in your applications will depend on your working environment. If you use the magnets at elevated temperatures, select the alloys that have a high intrinsic coercivity (Hci). If you use the alloy at lower temperatures (such as room temperature), you may select higher Br materials. Remember that if the magnet is being used in adverse conditions, such as repelling positions in motors where repelling magnetic fields are being used to drive the rotor and similar applications, selecting materials with moderate or high coercivity is recommended. Applications where fields are being used to trigger sensors, switches, and similar applications may use lower coercivity magnets.
Using the Neodymium Iron Boron magnet in cryogenic temperatures (below 200°C) is not recommended from our standard alloys; however, HSMAG does offer custom alloys for these applications. These custom alloys are available in limited quantities since they are extremely specialized and only produced in the lab. These advanced alloys can reach energy products in excess of 53 MGOe at cryogenic temperatures. For further information, please call the factory or contact your regional sales manager.
Since the Neodymium Iron Boron magnets are prone to rapid oxidation, salt spray, salt water, and hydrogen are very harsh on the magnet. Consider hermetically sealing the magnet if you wish to use NdFeB in such environments. For high reliability applications, familiarize yourself with the section “testing and certification” so that you understand the tests that are available. Some of these tests are used to predict how the magnet will perform over extended periods in the field.
HSMAG offers the world’s premium Neodymium Iron Boron alloys, advanced coatings, and the ability to provide fast production runs. Additionally, HSMAG can manufacture and fabricate entire assemblies, such as rotor or stator assemblies, couplings, and hermetically sealed components to your requirements. Design of magnetic circuits is also available.
Permanent Magnets are a class of materials that retains its magnetic properties after the applied field has been removed. There are a number of permanent magnet materials, and in each group there are many grades of materials.
NdFeB Magnets are characterized by three main characteristics. These are known as the:
(1) Residual Induction (symbol Br, and measured in Gauss). This is an indication of how strong the magnet is capable of being.
(2) Coercive Force (symbol Hc, and measured in Oersteds). This is an indication of how difficult it is to demagnetize the magnet.
(3) Maximum Energy Product (symbol BHmax, and measured in Gauss-Oersteds). This is an indication of what volume of magnet materials is required to project a given level of magnetic flux.
