Hard Ferrite Magnets

Hard ferrite magnets, also known as permanent ferrite magnets, are characterized by their strong magnetic properties and resistance to demagnetization.

Characteristics:

High Coercivity: Strong resistance to being demagnetized by external magnetic fields.
High Remanence: High residual magnetism, meaning they retain a significant amount of their magnetization after an external magnetic field is removed.
Brittleness: Typically brittle and can crack or chip if not handled properly.
Corrosion Resistance: Good resistance to corrosion, often used without additional coatings.

Applications:

• Loudspeakers: Used in speaker magnets due to their stable magnetic properties and low cost.
• Motors: Employed in various types of motors, including those in household appliances and automotive applications.
• Magnetic Separators: Used in industrial applications to separate magnetic materials from non-magnetic ones.
• Magnetic Assemblies: Utilized in various magnetic assemblies and holding devices.
