Y30 permanent ferrite magnet disc/ China Magnet Expert Y30 permanent ferrite magnet disc
Product Description:
Ceramic (ferrite) magnets are composed of SrO or BaO and Fe2O3. They are charcoal gray in color and usually appear in the forms of discs,rings,blocks,cylinders,and sometimes arcs or segments for motors.
Attributes of Ceramic Magnets:
• Least expensive material compared to alnico and rare earth magnets
• High intrinsic coercive force
• Available in simple shapes only due to manufacturing process
• Lower service temperature than alnico, greater than rare earth
• Lower energy product than alnico and rare earth magnets
• Most common grades of Y25,Y30,Y30H-1,Y30H-2,Y32,Y33 ceramic are 1, 5 and 8 (1-8 possible)
