Hard Ferrite magnet, magnetic assembly

Product Details

Hard Ferrite magnet is also known as a Ceramic Magnet and even as Permanent Ferrite magnet. The name is interchangeable but they all refer to exactly the same material type. They are known as Ceramic Magnets because they are electrically insulating. Hard Ferrite / Ceramic magnets composed of barium or strontium, were developed in the early 1960's as an alternative to the more expensive metallic magnets. This class of magnet is very hard, brittle and possesses lower energy characteristics compared to other magnetic materials. However, it is very popular and widely used in all industries, including Automotive, Aerospace, Military, Advertising, Design House, Electronic and Academic/R&D because of its excellent resistance to demagnetization, corrosion, and the advantageous pricing.
Hard Ferrite magnets are manufactured by pressing, sintering, or injection molding. These magnets can be both anisotropic and isotropic. 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.
