Since the 1950s, ferrite magnets have been mass-produced as an alternative to metallic magnets for their use in electromagnets, electronic inductors, and transformers.
Find out about ferrite magnets manufacturers that provide affordable yet sophisticated permanent magnet solutions for consumer, industrial, and commercial applications.
Ferrite magnets or SrO-6(Fe2O3) are more commonly known as ceramic magnets. It is a type of permanent magnet made from ferrite –– containing ceramic elements and iron oxide Fe2O3.
For its cost, ferrite magnets can be reliable in everyday applications because of their resistance to demagnetization and high magnetic permeability.
Ferrite magnets can either be isotropic or anisotropic:
The raw materials used to produce ferrite magnets are iron oxide and strontium carbonate, both highly abundant and economically available. The low production costs involved with these raw materials make ferrite magnets one of the most affordable and accessible permanent magnets for daily applications. They are usually made in simple shapes like squares, rectangles, cylinders, and rings.
To get high-quality ferrite magnets, we recommend finding a ferrite magnets manufacturer and supplier that carefully and meticulously follows the steps in the next section.
Ferrite magnets are produced by calcining a mixture of iron oxide with strontium carbonate or barium carbonate at extremely high temperatures between 1000 to 1350 degrees celsius. This will then form a metallic oxide.
To improve the magnetic performance of some ferrite magnet grades, other chemicals are added, such as cobalt and lanthanum.
Once the mixture cools, this fine powder is further milled to get fine particles smaller than 2 micrometers or 2 microns. Each particle will then consist of a single magnetic domain.
The fine powder is then pressed and compacted into a die.
To create an anisotropic magnet, the particles need to be mixed with water to form a slurry. Applying an external magnetic field to the process of sharpening and pressing will cause the magnet to be anisotropic.
Isotropic magnets will be formed if the magnet is dry-pressed and if no external magnetic field is applied.
Compacted particles will then be sintered at extremely high temperatures, causing the particles to fuse together, form a single magnet, and magnetized to saturation.
Using machines for ferrite magnets manufacturing can be costly with the use of diamond-coated machines. After machining, magnets are coated or plated for additional protection.
Finally, ferrite magnets are distributed by ferrite magnets manufacturers for commercial, industrial, and consumer applications. Before patronizing a ferrite magnets manufacturer, we highly recommend that you go with a factory that guarantees transparent documentation of their production line.
Ferrite magnets for sale are one of the most versatile and affordable permanent magnets today.
Here are some of the most common applications of Ferrite magnets in everyday life
In everyday applications, ferrite magnets provide affordable production of electroacoustic devices, including loudspeakers, headsets, microphones, guitar pick-ups, and electroacoustic sensors.
Ferrite magnets are widely used in the production of household machinery, including motors for food mixers, hand dryers, vacuum cleaners, treadmills, washing machines. They are also used in computer hard drives, DVD machines, treadmills, and air conditioners.
Ferrite magnets are increasingly used in smart technology items, including security systems, alarm systems, magnetic sensors, and levitation products, as well as electric curtains and automatic cleaning products.
Ferrite magnets suppliers manufacture these permanent magnets for commercial, industrial, and consumer applications in weighing sensors, motor speed sensors, car position sensors, car speed sensors, magnetron sensors, water flow sensors, and magnetostrictive displacement sensors.
Ferrite magnets are also used in motor equipment, including starter, fuel pump, wiper, fan, window swing, and lifting glass motors.
Ferrite magnets for sale are arguably the most affordable permanent magnets. They are widely used in DIY projects, fridge magnets, toys, and other novelty items.
They are also widely used in packaging and printing, crafts, and office supplies such as whiteboards and badges.
Ferrite magnets are an affordable alternative for industrial applications including lifting, fixing, clamping, positioning, fastening, and closure machines. They are also used as brakes, clamps, and pot magnets.
Ferrite magnets are also used for sweeper magnets, sea searcher magnets, and for large plate magnets that remove ferrous contamination in water, food, garbage, or raw material processing.
This technique is used to separate magnetic products from non-magnetic products.
Magnetic separation is a vital process in day-to-day global operations, including mineral and raw material processing, water treatment, garbage treatment, and food industry.
Ferrite magnets are widely used in power generators, alternators, and eddy currents. Some common applications are wind turbines, turbo generators, and wave power.
Flexible ferrite magnets are used in the medical industry for advanced diagnostic purposes, laboratory and surgical equipment, implants, prosthetics, drug delivery systems, and radiation shielding.
