    Coating for strong neodymium magnets 

    Sintered NdFeB has the strongest magnetic properties, but it has one of its biggest weaknesses, its corrosion resistance is too poor, so sintered NdFeB needs to be plated.Because the production process of sintered NdFeB is a powder metallurgy process, there will be small pores on the surface of the product. To make the plating layer more dense and improve the corrosion resistance, the passivation sealing treatment before plating is very important.

    Magnet Coating Types Display
    Support all magnet plating , like Ni, Zn, Epoxy , Gold, Silver etc. 

    Ni Plating Maget: Good anti-oxidation effect, high gloss apprearance,long servie life .t

    Common direction of magnetization showed in picture bellow:

    The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off. Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
    Common direction of magnetization showed in picture bellow:
    1> Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
    2> Rectangle shape magnets can be magnetized through Thickness, Length or Width.
    3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

    NdFeB Magnet Development Trends

    Sintered NdFeB magnets have been widely used in many fields such as the computer industry, automotive industry, medical equipment, energy transportation, etc. In addition, NdFeB magnets have been widely used in many new fields, especially in the low-carbon economy. Especially, under the trend of a low carbon economy sweeping the world, all countries in the world are paying attention to environmental protection and low carbon emission as the key science and technology field. This has put forward new requirements for improving energy structure, developing renewable energy, improving efficiency, energy saving and emission reduction, and advocating low-carbon life, which also provides a broad market space for the development of low-carbon economy industries such as wind power generation, new energy vehicles, and energy-saving home appliances. As the application becomes more and more widespread and the technology continues to develop, the sintered NdFeB used will have higher requirements. For example, the voice coil motor (VCM) of the mechanical hard disk for data storage requires N50H sintered NdFeB magnets with maximum magnetic energy product (BH) max> 48MGOe and Intrinsic Coercivity Hcj> 16kOe; while the ignition coil of automobile engine uses high performance sintered NdFeB magnets in the shape of thin sheet, which requires working temperature above 200 °C, which requires N35EH sintered NdFeB magnets to be used. In many emerging applications of sintered NdFeB magnets, such as the recent mechanical-minded walking robots, special motors with integrated technology, automotive automatic systems, etc., both high BH max and high Intrinsic Coercivity are required. The demand for high magnetic energy product (BH) max and high Intrinsic Coercivity is also high. Rare earth is an important strategic resource, and improving the comprehensive magnetic properties of sintered NdFeB magnets is beneficial to the efficient use of rare earth. Therefore, the trend of sintered Nd-Fe-B magnets is to increase the maximum magnetic energy product (BH)max and the Intrinsic Coercivity Hcj.
