    Rare earth magnets are an amazing invention that has revolutionized the way we use magnets. These magnets are incredibly strong and have brought about groundbreaking changes in the industries of technology, medicine, and even transportation.

    Neodymium iron boron magnetic materials are used to create rare earth magnets. These materials are known to provide a powerful magnetic field, which makes these magnets the strongest permanent magnets known to man. They are coated with different materials such as zinc, nickel and resin to protect them from rusting.

    What makes rare earth magnets so versatile is their ability to be customized in different sizes and shapes depending on their intended use. There are innumerable uses for these magnets in our everyday lives - from the small magnets used in our smartphones to the larger ones used in motors and generators.

    The magnetic field of rare earth magnets can also be customized to align the magnetic field along different axes such as the thickness or radial direction. This makes them ideal for a range of applications, from sensors to motors.

    Rare earth magnets have opened up new possibilities in industries such as medicine where they are used in MRI machines, and in transportation where they are used in electric vehicles and high-speed trains.

    Overall, rare earth magnets have brought about exciting advancements that have propelled us into the future. Their versatility and strength make them one of the most valuable inventions of our time.

    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.
