General Introduction

Ferrite magnet (Hard ferrite magnet) 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 magnet (Hard ferrite magnet) 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 resonance imaging and automotive sensors.

Besides industrial application, Ferrite magnet (Hard ferrite magnet) are widely use in Educational area.

What shapes can it be formed?

ceramic magnet, sintered ferrite magnet

Ferrite magnet is a kind of permanent magnet that made from iron oxide and barium or strontium carbonate by ceramic processing technology. So it's also called as ceramic magnet.

Special maching process needed for Ferrite magnet because it is brittle. Ferrite magnet can be made to different shapes and sizes by dry pressing then sintered, that is sintered ferrite magnet. Beside sintered ferrite magnet, bonded ferrite magnet(injection ferrite magnet) is existed. But sintered ferrite magnet are popular and widely used.

Ferrite magnet are the most commonly used permanent magnet material just because of its low cost, excellent corrosion and demagnetization resistance properties. Ferrite magnet can be made as isotropic and anisotropic. Isotropic if of the same magnetic properties in all direction, such as Grade-1. Anisotropic ferrite magnet must be magnetized in the direction of pressing.

By strength, ferrite magnet is stronger than AlNiCo magnet but weaker than neodymium magnet and SmCo (Samarium Cobalt ) magnet . Its working termperature is between from 40 degree to 250 degree. Because of these, ferrite magnet can be found in the application of separator and speaker and motor.
