Neodymium Cube Magnets 20mm

NdFeB alloy is the main component of this cube magnet that has dimensions of 20x20x20mm. If you need cube magnets with 17-25 kg magnetic force, neodymium magnet cubes 20mm are ideal ones, which is twice as big as that of the magnetic cubes 10mm and pull 37.5 - 55.7 LB on a steel plate. They are usually provided with Ni-Cu-Ni coating. Our neodymium magnet 20mm series are delivered with thicker plastic spacers so that you can, you can separate them easily. However, you still need to handle such super-strong cube magnets carefully.
