Neodymium magnet is also know as NdFeB or Neo Magnets these are made from Neodymium, Boron, Iron and other minor elements. Neodymium magnets are considered to be the strongest compared to Alnico, Samarium-Cobalt and Ferrite magnets.
Neodymium magnetic rods are usually used in separators and grates assembly that effectively separates ferrous contaminants from free flowing materials. Magnetic rods are made of strong inner core neodymium magnets and outer core of 304 or 316 stainless steel and can be fine polished for food grade and pharmaceutical standard. These magnets can be customized for different dimensions, gauss strength with both ends to be threaded holes, threaded, pointed ends etc. Standard working temperature is =< 80oC and the max can reach 350oC for special requirements. Maximum magnetic field strength can reach 12000 Gauss.
