Hard Ferrite ceramic magnets were developed in the 60’s and today comprise 75% of world magnetic consumption. Despite their relatively low magnetic values, they are the most popular magnet on the market due to ready availability and relatively low cost.
The raw material from which ferrite magnets are produced is Strontium Ferrite powder (mainly ScO.6Fe203) which is formed in a press while subjected to an electric field. This process allows the direction of the magnetic field to be determined during the production of the magnet.
Ferrite magnets main qualities: ferriteHigh coercivity (= high resistance of the magnet to demagnetization).
Highly stability under difficult environment conditions with no need for a coating to protect the magnet.
High resistance to oxidation.
Durability – the magnet is stable and constant.
Ferrite magnets popular uses: automotive industry, electric motors (DC, brushless and others), magnetic separators (mainly plates), home appliances and more.
HSMAG specializes in the production of Hard Ferrite (anisotropic) using a wet pressing process. Cutting and grinding of the magnets is performed with an electroplated diamond grinding wheel. Disc Sintered Ferrite Magnets
Buy ceramic disc magnets on-line today! We carry a large inventory of ceramic disc magnets, available in a wide range of sizes, not all of which are shown on this website. Ceramic magnets (also known as “Ferrite” magnets) are part of the permanent magnet family, and the lowest cost, hard magnets available today!
Ceramic magnet material is comprised of iron oxide & barium or strontium carbonate. Ceramic disc magnets exhibit relatively good holding strength, making them the popular choice for many consumer and commercial applications. Ceramic magnets are popular magnets for crafters, used for arts and crafts as well as modeling projects, as refrigerator magnets, science projects, POP displays, signage, jewelry clasps, furniture parts, motor components and much more.
Ceramic magnets can be custom cut or machined to your exact requirements, using our in-house manufacturing facilities and experienced team of engineers. Just let us know what you are looking for by sending us a request for quote or contact us today, and we’ll work with you to determine the most economical solution for your project.
