Nd-Fe-B magnet can be divided into two kinds of bonded and sinter.The bond is actually the injection molding molding and sintering of vacuum through high-temperature heating!
Ndfeb magnet has the strongest so far for magnetic force of permanent magnet, known as magnet king, with extremely high magnetic properties of its maximum magnetic energy product (10 times per cent) higher than the ferrite (ferrite BHmax.Its own mechanical processing performance is also quite good.The highest working temperature can reach 200°C.And its hard, stable performance, and has a good performance-price ratio, and their application is extremely wide.But because of its strong chemical activity, it must be on the surface of coating layer processing.(Such as Zn, Ni, electrophoresis, passivation etc.)
A low coercivity grade Neodymium magnet may begin to lose strength if heated above 176°F (80°C). High coercivity grade Neodymium Magnetshave been developed to function at temperatures up to 428Â°F (220°C) with little irreversible loss. The need for low temperature coefficient in neodymium magnetapplications has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade
Many grades of Neodymium exist to support a variety of industrial and commercial applications. The range of Neo grades is typically 33 to 52 MGOe. These ranges allow for balancing cost, magnetic performance, and operational temperature resistance
Although most commercial magnets are anistropic, which means they have a preferred direction of magnetization, various pole configurations can be achieved without conflicting with a Neodymium Magnet's orientation.
While today's Neo magnets are more temperature and corrosion-resistant, a protective coating is still necessary for certain applications.
