Neodymium Disc Strong Magnet – 10X2mm

Neodymium Disc Strong Magnet – 10X2mm provides an incredibly powerful magnetic force within a compact and versatile form factor suitable for precision engineering and creative projects. These Rare Earth magnets utilize a Neodymium-Iron-Boron (NdFeB) alloy to deliver the highest magnetic energy product available in the industry today. Consequently, they offer superior holding power compared to traditional ceramic or ferrite magnets of the same size. Designers and hobbyists can easily integrate these slim discs into assemblies where space is limited but high retention is required. Furthermore, the triple-layer Nickel-Copper-Nickel coating protects the material against corrosion and provides a smooth, aesthetic finish. Therefore, you should choose these 10x2mm discs for any application that demands reliable magnetic performance in a low-profile footprint.

Key Features:

• High Magnetic Grade: These magnets feature an N35 or higher grade rating, ensuring a high flux density and remarkable pull force for their small volume.
• Triple-Layer Coating: The Ni-Cu-Ni plating offers a durable shield against oxidation and environmental wear, extending the lifespan of the magnet significantly.
• Compact Profile: A thickness of only 2mm allows for discreet mounting in thin enclosures, magnetic closures, and precision sensors.
• High Coercivity: The material demonstrates excellent resistance to demagnetization, maintaining its strength even in the presence of external magnetic fields.
• Versatile Pairing: These discs work perfectly in pairs or with steel surfaces to create secure, reversible mechanical joints.
