Neodymium Disc Magnet – 25.4mm × 12.7mm | N45
The Neodymium Disc Magnet – 25.4mm × 12.7mm (N45) is a high-performance rare earth magnet designed for applications that demand exceptional holding power in a compact, cylindrical form. Manufactured from N45 grade neodymium, this disc magnet delivers significantly higher magnetic strength than standard ferrite or lower-grade neodymium magnets of the same size.
With a 25.4mm (1 inch) diameter and 12.7mm (0.5 inch) height, this magnet is axially magnetised (through the height), providing strong, concentrated surface attraction on both flat faces. The durable NiCuNi (Nickel-Copper-Nickel) coating offers excellent corrosion resistance while giving the magnet a smooth, professional silver finish.
