Neodymium-Ferro-Boron Magnets NdFeB
Neodymium-Ferro-Boron (NdFeB) is the most powerful magnet, with a maximum energy product going up to even more than 50 MGOe. As protection against corrosion Neodymium magnets are provided with a coating that can consist of Nickel, Nickel-Copper-Nickel, Zinc, Tin, Aluminium, Teflon or Epoxy. These magnets are used, among others, in motors, megaphones, separators, MRI scanners, windmills, electronics and vehicles, usually in combination with sensors.
- Pressed out of rare earth materials neodymium-iron-borium.
- Machine with diamond tools and cool with copious amounts of water.
- Provide highest magnetic force.
- Temperature range: standard up to +80 °C, specials up to +180 °C.
- Neoflux® magnets are usually made with a coating to protect against oxidation. A zinc or nickel coating is standard.
- Available on request: epoxy coating, tin coating, aluminium coating, nickel-copper-nickel or double coating.
- Available in a wide range of shapes and dimensions (without extra tooling costs).
- Available in standard and stabilized versions.
- Also available in plastic bonded version.
