Key Features
🧲 Super Strong Magnetic Force
Made of high-performance neodymium iron boron (NdFeB) material, this strong nickel coated magnet has excellent magnetic force, far exceeding that of ferrite magnets or other ordinary magnets of the same size. Suitable for heavy-duty holding, lifting and industrial applications.
One D40×20mm size neodymium magnet can generate up to 60 kg of pulling force, depending on the magnet grade(see table below) and the conditions of use.
