    Rare earth magnets are the strongest permanent magnet currently . They are composed of neodymium iron boron magnetic material and are plated in different materials,like zinc, nickel, resin etc, for the protection the magnet from rusty. Will do the magnetic field direction, like magnetized through the thickness or Radial, etc.  They  can be customized size and have innumerable uses.

    At any time, we welcome customers at home and abroad to visit, we will be in line with the principle of mutual benefit, looking forward to working with you to create brilliant!

    Production    Process 

    Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.



    Packing Details : Packed with white box, carton with foam and iron sheet to sheilding the magnetism during the transportation.

    Delivery Details : 7-30 days after order confirmation. Y



    Q: Are you trader or manufacturer? 

    A:We are a  neodymium magnet manufacturer of 20 years.  We have our own factory. We are one of the TOP  enterprises of the production of rare earth permanent magnet materials.

    Q: May I get some samples to test? 

    A: Yes, we provide samples. We could offer sample for free  if they are ready in stocks. But you would need to pay for the shipping cost.

    Q:How to ensure product quality? 

    A: We have 20 years  production experience and service experience in different markets. We work with many companies, like Disney, calendar, Samsung, apple and Huawei etc. We have a good reputation, although we can rest assured.
