18mm x 3mm Ferrite Disc Magnet (Dia 18mm, Height 3mm)

18mm × 3mm Ferrite Disc Magnet (Dia 18mm, Height 3mm)

This ferrite disc magnet is made from sintered strontium ferrite (ceramic), one of the most widely used and cost-effective permanent magnet materials available. With a diameter of 18mm and a height of 3mm, this is a large flat disc magnet that delivers a strong and evenly distributed magnetic hold across a wide surface area. The 18mm diameter makes it one of the more generously sized ferrite disc magnets, offering a reliable and stable hold suitable for a broad range of everyday and light industrial applications while still maintaining a slim low-profile design. Ferrite magnets are naturally resistant to corrosion and demagnetisation, making them a practical long-lasting choice for both indoor and outdoor use without any protective coating needed.
