Product Description
Universal (Ningbo) Magnetech Co., Ltd. Was founded in 1987. We are a professional manufacturer of permanent magnet products, including NdFeB, AlNiCo, SmCo, ferrite magnets, rubber magnet, magnetic lifter, magnetic chuck and other magnetic applications.

Our main magnets have maximum energy product from 27MGOe to 52MGOe, intrinsic coercivity force from 12KOe, 14KOe, 17KOe, 20KOe up to 27KOe for different working conditions. We can supply NdFeB permanent magnets in various sizes, shapes and dimensions at the requests of customers and will deliver them in the shortest possible time.

With expertise management, our products have been well received in many European and Asian countries. Our present production capacity is over 800 tons per year. If you are interested in any of our products, please feel free to contact us for more information.

Product Description
Neodymium Magnet (also know as NdFeB, NIB or Neo Magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the ND2Fe14B tetragonal crytaline structure. 

Neodymium magnets are the strongest type of permanent magnet made. They have replaced other types of magnet in the many applications in modern produces that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners. 

Grades of Neodymium magnets:

N35-N50(working temperature Max. 80) 
33H-46H(working temperature Max. 120) 
33SH-44SH(working temperature Max. 150) 
28UH-38UH(working temperature Max. 180) 
28EH-35EH(working temperature Max. 200) 

Some important properties used to compare permanent magnets are: Remanence(Br). Which measures the strength of the magnetic field; Coercivity 
(Hci), the material's resistance to becoming demagnetized; Energy product(BHmax), the density of magnetic energy; And Curie temperature(TC), the temperature at which the material loses its magnetism. Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Neodvmium is alloved with terbium and dysprosium in order to preserve its magnetic properties at high temperatures. The table below compaes the magnetic performance of neodymium magnets with other types of permanent magnets. 

Application of neodymium magnet: 

Magnets are found in almost all modern objects. The computer hard drive Most modern mobile phones now include a small neodymium magnet or two. Like computer compenents magnets have gradually become small and smaller making them easy to integrate into most industrial manufacturing processes. We also find that a lot of model and jewelley makers like our magnets as they fit easily into their models and allow parts to be easily removed and re-attached. For lifting. Holding, separating, and retrieving, we have the right magnetic assemblies and permanent magnetic materials for all types of industrial, OEM and commercial applications. Our expertise and ability to develop customized solutions will match the correct magnet for your application.
