FERRITE MAGNETS: Powerful and versatile
Ferrite magnets, also known as ceramic magnets, are a proven choice for numerous industrial applications due to their robust performance and versatility. They are made from a mixture of iron oxide and barium or strontium carbonate and are characterized by their high coercivity, which means they can maintain their magnetism even in the presence of an external magnetic field.
Applications of Ferrite Magnets
Ferrite magnets are widely used in various industries and technologies:
Motors and generators: Due to their high resistance to demagnetization, ferrite magnets are often used in the rotors of motors and generators.
Speakers: The ability of ferrite magnets to create a strong magnetic field makes them ideal for use in speaker and headphone magnets.
Magnetic separators: Magnetic separators use ferrite magnets to remove ferrous materials from a stream of non-ferrous materials.
MRI machines: In some MRI machines, ferrite magnets serve as the main magnetic field because they can generate a strong and stable magnetic field.
Automotive Applications: Ferrite magnets are used in various automotive applications such as sensors, electric power steering systems, and drive systems for hybrid and electric vehicles.
Technical data and features
The magnetic properties of ferrite magnets include:
- Maximum energy product (BHmax): Typically between 1 and 4.5 MGOe (Mega Gauss Oersteds)
- Residual induction (Br): Typically between 2,800 and 4,500 Gauss
- Coercive field strength (Hc): Typically between 1,800 and 4,000 Oersted
Ferrite magnets are relatively stable over a wide temperature range, with a maximum operating temperature of around 250–300 °C. They are brittle and can easily break or chip when subjected to impact or excessive stress, but they exhibit high corrosion resistance and are resistant to most solvents and chemicals.
manufacturing and molding
Ferrite magnets are manufactured using powder metallurgy, where powdered materials are pressed into the desired shape and sintered at high temperatures. They are available in various shapes such as discs, rings, blocks and sheets, thus offering a wide range of applications.
