Specification: Product name: high quality sintered hard ferrite magnet 1.Grade: y10t, y20, y25, y30, y30bh, y35 and etc. 2.Shape: disc, cylinder, block, ring, countersunk, segment, trapezoid, irregular shapes and more. Customized design (design proper magnets for clients specific requirements) 3.Sorts: we have disc ferrite magnets, segment ferrite magnets, ring ferrite magnets, block ferrite magnets, cylinder ferrite magnets, irregular ferrite magnets, sintered ferrite magnets, bonded ferrite magnets and many other series. High quality sintered hard ferrite magnet are manufactured by pressing, sintering, or injection molding. These magnets can be both anisotropic and isotropic. Anisotropic grades are oriented in the manufacturing direction and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction. The chemical composition is sro-6(fe2o3), strontium hexaferrite. The raw materials used to produce ferrite magnets are strontium carbonate and iron oxide both of which are readily available and low in cost. As a result, the use of ferrite magnets in most applications is more economical than other materials. Customized
