Standard Neodymium Magnets

Neodymium magnets (also known as Nd-Fe-B) is one type of rare-earth permanent magnet. And it is an important component for electric vehicles, house appliances, robots, garden tools, medical equipment, etc.

AH Magnet is specialized in researching, developing, manufacturing and exporting high-performance sintered neodymium iron boron magnets, 47 grades of standard neodymium magnets, from N33,N35 to 35AH, N52, and GBD Series from 48SH to 45AH are available. All magnets are widely applied to electric motors such as servo motors, stepper motors, brushless motor, linear motors, permanent magnet synchronous motors, etc.

Aim to increase the corrosion resistance of sintered neodymium iron boron magnets and to meet the designated surface requirements, we provide the normal coating layers, like nickel-coating, zinc-coating, epoxy-coating, aluminum-coating and passivation. We also customized composite coating to ensure durability of magnets according to different design and application environment of permanent magnets.

Find the suitable NdFeB to meet your design requirements from the following sheet and download the related files. And FIVE important keys should be considered when you choose from these grades.
