Ceramic (Ferrite) Magnets

Request for Quote

The Most Widely Used Permanent Magnet Materials Used Today

Custom Ceramic Magnets

Ceramic (ferrite) magnets are sintered permanent magnets, composed of Barium or Strontium Ferrite. Part of the rare-earth magnet family, ceramic magnets were developed in the 1960’s as an inexpensive alternative to metallic magnets and are now the most widely used permanent magnet materials used today.

Commonly referred to as “hard ferrite” magnets, ceramic (ferrite) magnets have a high resistance to demagnetization and oxidation, are relatively strong and very low cost compared to other permanent magnets. As a result, ceramic magnets are extensively used for a wide range of industrial, commercial and consumer applications.

Custom (Ferrite) Ceramic Magnets

Integrated Magnetics specializes in the technical design, engineering, manufacturing assembly and testing of custom ceramic (ferrite) magnets and precision magnetic assemblies. We routinely build technical magnetic assemblies, either as build-to-print or design-to-specification. We also stock a wide range of ceramic magnets in various grades, shapes and sizes which can be purchased online at Magnetshop.com. Send us a request for quote or contact us today to discuss your project’s specialty requirements.


Ceramic Magnets for Motors & Generators

Ceramic (Ferrite) Magnet Applications

Ceramic (Ferrite) magnets are hard, brittle and have lower coercivity than some of the other permanent magnet materials, however, because of their low cost and high-resistance to demagnetization and oxidation, they are a popular choice for numerous industrial, commercial and consumer applications. They are routinely used in DC brushless and permanent magnet motors, alternators and generators, for security systems, lifting and holding applications, POP displays, commercial signage, magnetic separators, magnetic resonance imaging, automotive sensors, and countless other applications. We are trusted partners to businesses worldwide in these primary industries.

Ceramic (Ferrite) Magnets Features & Characteristics

  • Grades & Materials - We carry a large inventory of licensed, ceramic (ferrite) magnet materials in standard and premium grades for reduced production and lead times. We offer sintered Ceramic magnets in grades that range from 1.1 MGOe to 4.5 MGOe. Visit our Ceramic magnet materials page for additional information and for data sheets about this material.

  • Sizes & Shapes - Standard ceramic (ferrite) magnet shapes include discs, blocks, rings, and arc segments in a variety of sizes and grades. Non-standard shapes can also be custom fabricated to blueprint specifications from raw stock. We can custom manufacture ceramic (ferrite) magnets in virtually any shape and size to meet your project’s exact requirements.

  • Temperature Considerations - Properties for ceramic magnets degrade linearly with temperature. At 350°F (177°C), about 75% of room temperature magnetization is retained, and at 550°F (288°C), about 50% is retained.

  • Manufacturing Methods - Ceramic magnets are extremely brittle, so they are prone to chipping and cracking. Therefore, special machining techniques involving diamond-grinding must be used to machine this material prior to magnetization. We are fully equipped to machine these materials to your project’s specialty requirements.Visit our ceramic magnet materials page for more detailed information on ceramic machining techniques.

  • Surface Treatments - The corrosion resistance of Ceramic (Ferrite) is excellent, therefore special coatings to prevent corrosion or oxidation are not required.

  • Magnetizing & Assembly Considerations - Ceramic magnets are anisotropic, and can only be magnetized in the orientation direction. Magnetizing fields in excess of 50 kOe are required to saturate these materials.

  • Handling & Storage - Ceramic (Ferrite) magnets are very hard and brittle and will shatter if dropped. Therefore, special care must be taken when handling these magnets to avoid injury to personnel and damage to the magnets.
