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 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.
Remanence (Br): N45 neodymium cube magnets 20x20x20mm have remanence of 13200-13800Gs.
Coercivity (HcJ): Hcj of 20mm neodymium cube magnets N45 is over 12Koe (955KA/m).
Magnetic Energy/ (B-H)max: (B-H)max range of neodymium magnet 20mm is 43- 46 MGoe .
Operating Temp.: Maximum withstand 80℃ .
Available Coating: Nickel, Zinc, Epoxy, Gold, Silver, Teflon, Plastic, Rubber are available for these neodymium cube magnets for sale.
