Economical: These ceramic magnets are an economical alternative to magnets. Only a fraction of the cost of similar sized rare earth magnets. Durable: They will not rust in any environment. Suitable for use in fresh or salt water. The magnetism will always continue to work properly. APPLICATIONS: Science education in schools, science projects for children, i.e. suspended trains, crafts at home, light work in the backyard or garage, etc. Ferrite magnets are dark gray and are often referred to as having a “pencil lead“ appearance. Ferrite/ceramic permanent magnets are technically known as hard ferrite materials. They are different from the soft ferrite materials used in transformer cores. The high coercivity of ferrite magnets means they are classified as hard materials, just like all other permanent magnets. Ferrite magnets are very popular because of their properties. Ferrite magnets are non-corrosive - excellent long-term performance; if cared for, they can outlast the life of most products. Ferrite magnets can be used up to 250 degrees Celsius (in some cases up to 300 degrees Celsius). The cost of ferrite magnets is also low, especially in high-volume production. Compared with other permanent magnets, ferrite magnets have high hardness, high brittleness, and low energy. But it is not easy to be demagnetized and corroded, the production process is simple, and the cost is not high. Therefore, in the production of the entire magnet industry, ferrite magnets have the highest status and are widely used in industrial production. In contrast, permanent ferrite magnets are made of hard ferrite and have a high coercivity and high remanence after magnetization. Iron oxide and barium or strontium carbonate are used to make hard ferrite magnets. High coercivity means that these materials are highly resistant to demagnetization, an essential feature of permanent magnets. They also have high magnetic permeability. These so-called ceramic magnets are cheap and widely used in household products such as refrigerator magnets. If you want to know more information, please go to Or you can send email to: blanca@
