Cylindrical Neodymium magnet is a kind of permanent magnet based on inter-metallic compound Nd2Fe14B. The main components are rare earth elements neodymium (Nd), iron (Fe), boron (B). NdFeb is an alloy material that is one of the strongest magnetic materials, with a magnetic energy constant of 1400 kJ/m3, high temperature stability, corrosion resistance and impact resistance.

This is a cylindrical magnet with the diameter 3mm and the height is 5mm. Cylindrical Ndfeb is also known as a magnetic rod, its length is usually longer than the diameter, and normally the direction of magnetization is radial magnetization. It has high magnetic properties and attractive, and is very light, so it is widely used in various electronic products, medical equipment, magnetic switch and other industries. The surface of the cylindrical iron-boron magnet has an oxidized surface that resists corrosion, and this material has good corrosion resistance, allowing it to adapt to different environments.

Neodymium cylindrical magnet 3x5mm

Super strong rare earth neodymium cylindrical magnets can be customized according to your requirements of different sizes and tolerance of magnets, while can be also customized by different grades of materials. It has strong magnetic properties and extremely high magnetic properties. In practical applications, it can be used as a magnetic control device for electronic products and a device for separating electromagnetic waves.
