Permanent magnet disc is a very popular and common shape products. We’ve been exported magnets for more than 50 countries, we built good reputations all over the word. This neodymium magnets size diameter 12mm with height of 5mm, magnetized through axial, nickel coating, this magnets is applied for industry to combine with an iron metal plate. Each plate use 4pcs magnets to hold on another iron equipment. Since the metal itself is heave, normal low grade of N35 can not produce enough pulling force. This N52 grade strong magnets, produce 10.7lb force. Surface gauss is more than 4000. Of course, to choose the right grade of magnets for your application is the most important. Please feel free to contact us for your better choice of the customized magnets.
