精品文档 1欢迎下载 HARDHARD FERRITEFERRITE MAGNETSMAGNETS Hard ferrite ceramic magnets were developed in the 1960 s as a low cost alternative to metallic magnets Even though they exhibit low energy compared with other permanent magnet materials and are relatively brittle and hard ferrite magnets have won wide acceptance due to their good resistance to demagnetization excellent corrosion resistance and low price per pound In fact measured by weight ferrite represents more than 75 percent of the world magnet consumption It is the first choice for most types of DC motors magnetic separators magnetic

Since they are made from Neodymium one of the most plentiful rare earth elements and inexpensive iron NdFeB magnets offer the best value in cost and performance NdFeB magnets are available in both sintered and bonded forms Sintered NdFeB offers the highest magnetic properties 28 MGOe to 50 MGOe while Bonded NdFeB offers lower energy properties Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets they can be made in shapes and sizes that are difficult to achieve with sintering A variety of coatings can be applied to the magnets surface to overcome the principle drawback of neodymium based magnets their tendency to corrode easily Max Energy Product Remanence Coercive Force Rev Temp Coeff Curie Temp Working Temp BH max Br Hc Hci Bd Hd Tc
