The long and round shape sintered NdFeB magnets are give the name of neodymium(NdFeB) cylinder magnets. Differ from normal disc shape,the size of thickness is larger than its diameter. NdFeB cylinder magnet is expressed by diameter(D) x length(L).
The cylinder shaped magnets resembles a cylinder with a corrosion-resistant oxide surface, exhibiting excellent corrosion resistance for diverse environments. These rare earth neodymium cylinder magnets excel in magnetic performance, low-temperature stability, corrosion resistance, and impact resistance. Customizable in various sizes, these neodymium cylinder magnets can be tailored to customer requirements with different material grades.
Strong NdFeB cylinder magnets are easy to corrode, and electroplating is needed for rust-resistant, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper-nickel, environmental protection nickel copper-nickel, epoxy coating, etc.

The magnetized direction of powerful neodymium(NdFeB) rod magnets is generally divided into axially magnetized and diameter magnetized, which is determined according to the required working face.
Known for high magnetism and compactness, cylindrical NdFeB magnets find wide applications in electronics and equipment. Their strong magnetic properties make them suitable for electronic control devices and electromagnetic wave separation. These neodymium cylinder magnets enhance directional control in transportation, improving vehicle safety and stability.
Additionally, rare earth cylinder magnets can optimize wind and solar power generation efficiency by controlling the orientation of turbines and solar panels. Furthermore, cylindrical NdFeB magnets enhance the performance and precision of electronic products, such as power tools, automation equipment, and electronic devices.
