Exhibits characteristics in severe environments such as rust and high temperatures!

Ferrite magnets are made by grinding iron oxide into a fine powder, then forming and sintering it. Anisotropic ferrite magnets are magnets that have strong magnetic force in a specific direction only. Due to their reasonable price, anisotropic ferrite magnets are currently the most popular magnets widely used for various applications. They have relatively stable magnetic properties and are characterized by their resistance to rust. When used in environments below -30°C, caution is needed regarding low-temperature demagnetization. Additionally, they have low mechanical strength and are brittle like ceramics, so care must be taken when handling them.
