18mm x 5mm Ferrite Disc Magnet (Dia 18mm, Height 5mm)

18mm × 5mm Ferrite Disc Magnet (Dia 18mm, Height 5mm)

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 5mm, this disc magnet combines a large surface area with a greater thickness, delivering a noticeably stronger pull force and deeper magnetic field penetration compared to thinner disc magnets of the same diameter. The combination of the wide 18mm diameter and the 5mm height makes it an excellent choice for applications where both surface coverage and holding strength are important. 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.
