Ferrite Discs

Eclipse Magnetics Ferrite Disc Magnets are solid, circular magnets made entirely from ferrite (ceramic) magnetic material, providing a cost-effective and corrosion-resistant solution for a wide range of magnetic applications. These discs are uncoated and non-encased, making them ideal for use where the magnet will be embedded, enclosed, or installed in protected environments that don’t require mechanical shielding.

Renowned for their high resistance to demagnetisation, chemical stability, and strong performance at elevated temperatures, Eclipse Magnetics Ferrite Discs are a reliable choice across industrial, commercial, and hobbyist settings. While not as powerful as neodymium magnets, their consistent and dependable performance makes them perfectly suited for light to medium-duty holding, spacing, and magnetic repelling tasks.

Simple, durable, and versatile, these ferrite disc magnets deliver long-lasting magnetic strength and stability — ideal for everyday use or large-scale manufacturing applications.

Key Features

• Solid ferrite (ceramic) construction: ensures stable and consistent magnetism over time

• Cost-effective design: ideal for bulk use and high-volume production applications

• High temperature resistance: maintains performance in elevated heat conditions

• Corrosion-resistant: chemically stable and reliable without the need for coatings

• Axial magnetisation: north and south poles on flat faces provide uniform holding or repelling force

• Durable yet brittle material: best suited for enclosed, embedded, or protected installations

Learn More About Ferrite Discs

Ferrite Discs are one of the most widely used types of permanent magnets, valued for their reliability, low cost, and versatility. Made from a blend of iron oxide and ceramic materials, ferrite (also know as ceramic) magnets are hard and brittle, but offer excellent magnetic stability, especially in environments where heat, moisture, or chemicals are present. 

These magnets are typically axially magnetised, meaning the magnetic poles are located on the flat circular faces, which makes them ideal for face-to-face holding or repelling in stacked configurations. Since ferrite doesn't corrode, it's commonly used in exposed environments or embedded within devices or fixtures. 

Although they don't have the high pull force of neodymium magnets, ferrite discs are perfectly suited for light to medium-duty applications where magnetic strength isn't the top priority such as low-cost appliances, learning aids, or magnetic separation systems. 

Their simplicity, availability in many sizes, and natural durability make them a smart choice for businesses, educators, manufacturers, and DIYers who need dependable magnets that perform without the premium price tag.
