FERRITE BLOCK MAGNET

Description

Ceramic magnets, also known as ferrite magnets, hold a prominent position in the world of magnets due to their widespread popularity and versatility. These magnets, characterized by their dark grey or lead-like appearance similar to a pencil, are hard, brittle, and typically uncoated, often bearing a fine powder residue. Featuring precisely cut edges and fine 90° corners, our medium-strength ferrite block magnets can withstand temperatures up to 250°C, making them suitable for a variety of high-temperature applications. With their robust ceramic construction and corrosion-resistant properties, they are well-suited for both indoor and outdoor use, including in water, saltwater, and marine environments.

Manufactured from iron oxide and barium or strontium carbonate, ferrite magnets are man-made magnets with high coercivity, rendering them highly resistant to demagnetization—an essential characteristic for permanent magnets. These magnets find widespread use in applications requiring a permanent high-strength magnetic field, such as loudspeakers, and are renowned for their long-term performance when properly maintained.

While often referred to as ceramic magnets, the term “ceramic” underscores their electrical insulating properties, as they exhibit exceptionally high electrical resistance, unlike other ferromagnetic materials. Ferrite magnets are commonly employed across various industries, including automotive, sensor technology, aerospace, military, advertising, electronics, academia, and research and development. In hobby and craft applications, as well as model building, smaller ferrite block magnets are frequently utilized, while larger block magnets are favored in ferrous separation applications, such as removing metal contamination from conveyor belts in food distribution plants.

It’s important to note that ferrite magnets are hard and brittle and may shatter or break if mishandled or dropped. Visual imperfections such as cracks and lines are common and generally do not indicate defects, with chips and cracks within acceptable limits as specified.

In summary, ceramic magnets find application across a wide range of industries, from simple uses like fridge magnets, magnetic locks, sweepers, and separators to more complex applications such as generators and eddy current devices. Their versatility and reliability make them indispensable in numerous applications across various sectors.
