Ferrite magnets or Ceramic Magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost.
Ferrite magnets are very hard and brittle and require specialized machining techniques. Moreover, they should be machined in an unmagnetized state. We have equipped to machine these materials to specifications.
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, although some degree of greater magnetic strength will be found in the pressing dimension, usually the shortest dimension.
Due to their low cost, Ferrite magnets enjoy a very wide range of applications, from motors and loudspeakers to toys and crafts, and are the most widely used permanent magnets today. Block C8 Hard Ceramic Magnet

CERAMIC
CERAMIC PERMANENT MAGNETS ARE AN ECONOMICAL CHOICE FOR A WIDE RANGE OF APPLICATIONS. CERAMIC MATERIALS PRODUCE STRONG MAGNETIC PROPERTIES, AND IS AVAILABLE IN CUSTOMIZABLE SHAPES AND SIZES.
Ceramic magnets can be either isotropic or anisotropic. Isotropic ceramic magnets can be magnetized in any direction while the anisotropic ceramic magnets can only be magnetized through the easy axis (magnetization direction). They have very high electrical resistivity (around 106 Ohm-cm) and positive reversible temperature coefficient of intrinsic coercivity.

Ceramic maximum energy product, (BH)max, is lower than other permanent magnets, so they are typically much larger magnets in actual application. By weight, they are the most widely used magnet globally. Ceramics are chemically stable and the least expensive magnets due to inexpensive raw materials and processes. Maximum energy product, (BH)max, of 1 to 4 MGOe, is lower than that of rare earth magnets but intrinsic coercivity, Hci, from 2500 to 4000 Oersteds, (higher than Alnico). Ceramic magnets are a cost-effective choice in many industrial applications. Block Rectangular Hard Ferrite Permanent Magnets 35X15X5mm
