The flat and round shape strong NdFeB magnets are give the name of neodymium disc magnets, the size of diameter is larger than its thickness. Neodymium disc magnets are the preferred magnetic product in both industrial and consumer applications.
Due to their versatility and cost-effectiveness, these round rare earth magnets dominate the market and various industries as the most commonly used powerful magnet type. They are extensively employed in electric motors, speakers, and various sensor types. We offer neodymium round magnets in a range of thicknesses and sizes, with different coatings such as zinc, nickel, silver, gold, epoxy resin, etc.
Durable neodymium disc magnets are prone to corrosion, necessitating surface coatings. Commonly used coatings include zinc plating, nickel, eco-friendly zinc, eco-friendly nickel, nickel copper-nickel, eco-friendly nickel copper-nickel, and epoxy coating.

The magnetization direction of powerful NdFeB disc magnets is typically categorized as axial or diametrical, determined by the desired working face. Specify your magnetization preference when placing an order.
NdFeB magnets stand as unique, non-standard rare earth magnetic products. Sintered Nd-Fe-B material, with its excellent machinability, allows customization into various sizes of round shaped neodymium disc magnets. No molds are required for crafting robust neodymium disc magnets, and we cater to orders of any quantity, whether small or large.
