Ceramic blocks (sometimes called Ferrite block) are available in several different sizes. Ceramic/Ferrite magnets are a low cost but versatile and multipurpose type of magnet. Large ceramic block magnets are often used in sweeping and separation applications. Smaller ferrite blocks are commonly used in motors. Any machining of ferrite blocks must be done with a diamond wheel, ideally before magnetization, as they are hard and brittle. These are medium strength magnets.
Most of the mass production ferrite magnets is basically custom made ferrite magnets. Ferrite magnets are made according to the customer requirements. The tooling that is required to produce these magnets are specifically made and used only to manufacture this specific item. It enables to manufacture the magnets more precisely with less mechanical impacts. It is a simple rule, good mold equals less grinding. Less grinding to ceramic magnets is less cracks and chips.

Each custom made magnets has its own special requirements and characteristics. It can be different magnetic properties. a different grade or finishing. Each customer has his own magnet fitted to his application and assembly line. corners could have different radiuses. The phases could have different finishing, sizes and even tolerances.custom made ferrite magnets. Permanent Ceramic Magnets Block Shape

Mass production should be efficient to benefit both customer and manufacturer. Customer that order custom made magnets can control shape, size, tolerances, finishing, magnetic orientation, its magnetic properties and more. Off course, the idea is to perfectly match your magnets to your application and manufacturing process. Magma specialized in custom made ferrite magnets. Please have a look in our “how to order magnets” section for more information, or contact us and we will be happy to support your company.

Ferrite magnets, and all permanent magnets, are used because of their magnetic properties. Ferrite magnets properties mean their magnetic properties. Different grades of ferrite magnets have different magnetic properties. You can find explanations about the parameters (remanence, Coercive Force, maximum energy and more) in our magnet glossary page. Ceramic magnets are available in both oriented (anisotropic) and non-oriented (isotropic) grades. Most of the magnets sold by Magma are oriented (anisotropic). You will find in this page 3 types of grades (European, American & Chinese). Usually, customers are not asking for specific grades. Customers are looking for specific magnetic characteristics (the drawing of the magnet will specify the requested remanence / Br).
