Ferrite Disc Magnet - 18mm x 5mm

Ferrite Disc Magnet - 18mm x 5mm

Dependable, durable, and cost-effective, this Ferrite Disc Magnet measures 18mm in diameter x 5mm in thickness and is manufactured from premium ferrite magnetic material. Designed for reliable everyday performance, this permanent magnet is ideal for industrial, commercial, educational, and DIY applications where corrosion resistance, affordability, and long service life are key requirements.

Ferrite magnets are one of the world's most commonly used permanent magnet materials due to their excellent resistance to corrosion, oxidation, moisture, and demagnetisation. Unlike neodymium magnets, ferrite magnets require no protective coating, making them a low-maintenance solution suitable for both indoor and outdoor environments.

Magnetised through the 5mm thickness (axially magnetised), this ferrite disc magnet generates a consistent magnetic field across its flat circular faces. Its practical dimensions make it suitable for magnetic catches, displays, workshop fixtures, product assembly, educational equipment, craft projects, and general-purpose holding applications.

Please Note

Ferrite magnets are hard and durable but can be brittle if dropped or struck. While ferrite magnets generally provide lower magnetic strength than neodymium magnets, they offer exceptional corrosion resistance, long service life, and outstanding value for money. Keep away from children, pacemakers, sensitive electronic devices, and magnetic storage media. Holding strength will vary depending on the application and the characteristics of the steel surface being attracted.
