Features
Honsen offers neodymium magnets in square and rectangular blocks. These neodymium Iron Boron magnets are widely used for motor, sensor and holding applications. Neodymium block magnet is the most powerful rare earth magnet, which provides huge cost and performance return. It has the highest field / surface strength (Br) and high coercivity (Hcj), and can be easily machined to various shapes and sizes. It is an ideal choice from industrial and technological applications to your projects. Contact us for an efficient magnet solutions for your project. • Neo magnets are the most powerful commercially produced magnets. • Permanent Nib magnets are hard and brittle and may chip or break if dropped. • Honsen Neodymium block magnets can be magnetized through the length width and thickness. • Uncoated rare earth magnets may corrode in humid conditions. • Operating temperatures vary among material grades. For a comparison of neodymium material grades, please visit our chart of material properties.N Grade Magnets | ||||||
