    What is sintered neodymium magnet?
    What is sintered neodymium magnet? 1.Manufacturing porcess: The sintered NdFeB permanent magnet adopts a powder metallurgy process. The smelted alloy is made into powder and pressed into a compact in a magnetic field. The compact is sintered in an inert gas or vacuum to achieve densification. In order to improve the coercivity of the magnet,usually requires an aging heat treatment. 2.Chemical Comp...

    What is supporting the price hike amid tightened supply of rare earth material?
    In recent weeks, the domestic rare earth market as a whole prospered evidenced by overall rising prices of all products. In particular, the price of praseodymium oxide increased significantly among others. In the middle and late June, the market prices of praseodymium rallied, and terbium bottomed out. Later, since mid-July, market prices of light and heavy rare earth rose across the board, and th...

    What are the main factors that affercts the performance of NdFeB Magnets?
    1.Temperature Since sintered NdFeB magnet possess a negative temperature coefficient,the instantaneous or the continuous highest temperature of the working environment will give demagnetization in different and certain percentage,including reversible and irreversible,recoverable and unrecoverable demagnetization. 2.Humidity Sintered NdFeB magnet itself is easy to be corroded,rusted and oxidized,we...

    How to detect the quality of magnet's coating
    In order to improve the corrosion resistance of neodymium magnets and meet specific surface condition requirements,magnets need to be electroplated.The quality of the coating will affect its service life. The main detections are as follows: 1.Visual inspection 2.Check the thickness of coatings 3.Drop test (mainly among the Zinc plated products) 4.Crosscut test (mainly among the Nickel plated produ...

    How to select the coating of NdFeB magnet?
    Sintered NdFeB magnets are relatively inferior on corrosion resistance comparing with the traditional magnets such as Sm-Co,Alnico and ferrite. For general applications,sintered NdFeB magnets may need to be coated or surface treated depending on their intended uses.Coating treatment for the sintered NdFeB magnets not only improves their corrosion resistance,but also appearance,wear resistance as w...

    The advantages of neodymium magnet
    Sintered neodymium magnet are based on the inter-metallic Nd2Fe14B which has a very high Br and Hcj. High energy density makes neodymium magnet widely used in the modern industry and electronic applications,which makes instruments, generators,magnetic separators and other products become more smaller,lower weight and thinner. The advantages of neodymiuc are high cost/performance ratio and good mec...
