Hard Ferrite Magnets, aka Ceramic Magnets, are permanent magnet materials composed of Iron Oxide (Fe2O3), Barium (Ba) or Strontium (Sr) or any combination of the two. Ceramic magnets are the lowest cost permanent magnet, while providing good resistance to demagnetization.
Ferrite C5 and Ferrite C8 are the most widely used Ceramic Magnet Grades. Due to their low cost, Ferrite magnets are used in a wide range of applications, including motors, loudspeakers, and industrial applications. They are the most widely used type of permanent magnet.
Samarium Cobalt magnets are the second strongest rare earth magnet compared to Neodymium magnet material. Samarium Cobalt magnets, also known as SmCo, have better temperature stability and are extremely resistant to demagnetization. However, they are brittle, and prone to cracking and chipping.
Samarium Cobalt magnets are mainly used in the high-end applications which require high operating temperature between 250° and 350°C, such as aerospace and medical applications.
Alnico magnets are composed of aluminum, nickel, and cobalt. The main advantage of Alnico is its’ low temperature coefficient and the wide operating temperature range from – 273°C to 400°C.
Alnico 5 and 8 are anisotropic grades, designed to produce high magnetic output in a specified direction. The magnetic orientation is achieved during heat treatment.
