Ceramic Magnets
What Is Ceramic Magnet?
Ceramic (Ferrite) Magnet Is the Cheapest Industry Magnets
Due to relatively low-cost raw materials and an uncomplicated production process, permanent ceramic ferrite magnetsare considered the most cost-effective industrial magnet with the highest output. These ceramic neodymium bar magnets, also referred to as ceramic magnets, are presently the most common permanent magnetic material employed. Ferrite magnets are utilized in various applications, from motors and speakers to toys and other consumer and industrial products.
Ceramic (Ferrite) Magnet Is Rust (Corrosion) Resistant Magnet
Do ceramic magnets rust? Ferrite (ceramic) magnets exhibit excellent resistance to rust and corrosion, even when submerged in water. They are highly resistant to the harmful effects of a range of substances, including dilute acids, alkaline solutions, organic solvents, and certain hydroxides. These hard ferrite magnets attributes make them ideal for use in saline environments, as they are not susceptible to corrosion at all. Typically, the surface of ferrite magnets does not require any electroplating treatment or protective coating.
Ferrite Permanent Ceramic MagnetHas Medium Magnetic Strength
The magnetic energy product of ferrite magnets typically ranges from 1.1MGOe to 4.0MGOe. In comparison to rare earth magnets, ferrite magnets possess a relatively weak magnetic force, although their magnetic force is stronger in comparison to various other soft magnetic materials. As such, magnets ferrites are regarded as a permanent magnet material with medium magnetic strength. By utilizing ferrite magnets, significant cost savings can be achieved when a very strong magnetic force is not required.

Details of Ceramic Magnets
Ceramic magnets (also referred to as ferrite magnets) are sintered permanent magnet materials made from SrO or BaO, and Fe2O3. MEANK ceramic magnets are made of high-quality materials and are reliable and durable. This material can be categorized into anisotropic and isotropic ceramic magnets. The anisotropic ferrite magnet requires magnetization in one direction, while the isotropic type can be magnetized in any direction. Although the magnetic energy product of ferrite magnets ranges from 1.1moe to 4.0moe, making them less magnetically powerful than other permanent magnets, they exhibit strong anti-demagnetization properties and are available at a lower cost.
What Are Ceramic Magnets Used For
Ceramic (ferrite) magnets have excellent oxidation resistance and usually do not need additional protective coatings. They are the lowest cost hard magnets available at present. They are the first choice for all kinds of consumer goods and industrial applications. Common applications of ceramic magnets include:
