Y30 Block Ferrite Magnet For Loudspeaker And Conveyor
Description
Hard ferrite magnet, made by molding powder mixture of about 80% Fe2O3 and about 20% either BaCo3 or SrO3, is also called ceramic magnet. Along with deepening of research, some additives such as cobalt (Co) and lanthanum (La) are mixed together to improve the magnetic performance. The molded powder metallic green is sintered inside a temperature controlled furnace what is heated with electricity or coal. Though hard ferrite magnet is with low magnetic property, it is still a preferable choice to engineer in their design due to several factors: abundantly available raw material,the cheapest cost among permanent magnet family, low density, excellent stability of chemistry, high maximum working temperature and Curie temperature.
Applications
Sintered ferrite magnets are widely used in many different applications, such as motors, cars, magnetic selection loudspeakers, conveyor, and many special applications
