Ceramic Magnets

Ceramic or Ferrite Magnets are a low cost, light weight, and have a relatively high energy product that are part of the permanent magnet family. Iron oxide and strontium carbonate, the two materials in Ceramic Magnets, are easily attainable and available at lower costs than other materials used to make permanent magnets. Being less expensive is one reason ceramic magnets are more popular among the permanent magnets. Another reason for Ceramic Magnet's popularity is the ability to withstand operating temperatures of up to 480°F. Common applications include: Numerous manufacturing or home applications, speaker magnets, motors, reed switches, and Hall-Effect devices. Ceramic Magnets are made using a sintering process. The wet milling process produces slurry which is fed into a die. This material is pressed into a product which is later sintered at a high temperature. Once cooled, ceramic magnets are ground and cut to desired shapes. The most popular ceramic grades are 5 and 8. Grades 5 and 8 are considered anisotropic grades. This means they are only magnetized in the direction they are pressed. Anisotropic grades are the most powerful. Ceramic Magnets come in several forms. These ferrite magnets have a wide variety of applications such as: Speaker Magnets, DC Motors, Sweepers, Magnetic Separators for ferrous materials, Automotive Sensors, MRI’s, Reed Switching, and Hall Effect devices in assemblies. Ceramic Magnets are brittle and break easily. Because of this, you must be aware that it could chip, break, or even shatter if dropped or allowed to jump to something it is attracted to.
