Characteristics of neodymium-Iron-Boron magnets and process technology

ND-Fe-b magnetic material, as a result of latest development of rare earth permanent magnet materials, because of its excellent magnetic properties and was known as "magnetic." ND-Fe-b magnetic material is neodymium, iron oxide and other alloys. Also known as the magnet. Neodymium-Iron-Boron has a very high magnetic energy product and straightening force and high energy density makes neodymium-Iron-Boron permanent magnetic material in modern industry and electronic technology has been widely applied, thus enabling instrumentation, electro-acoustic electric, magnetic separation of magnetic devices such as miniaturization, light weight and thin as possible. The advantages of ND-Fe-b is cost-effective, with good mechanical characteristics; Yu Juli temperature is insufficient in low temperature characteristics is poor, and easy to corrosion of powder, must adjust its chemical composition and surface treatment methods make it possible to improve to meet the application requirements.
