The round neodymium magnet 203 mm is a slim yet powerful permanent magnet designed for applications that require strong magnetic holding force with minimal thickness. Manufactured from high-quality neodymium iron boron (NdFeB) and finished with a protective silver nickel coating, this magnet delivers excellent performance, durability, and corrosion resistance.
With a 20 mm diameter and 3 mm thickness, this disc magnet provides a larger contact surface while maintaining a low-profile design. It is well suited for electronics, signage, access panels, sensor mounting, 3D printing projects, enclosures, and general DIY or workshop use.
The flat, smooth surfaces ensure reliable magnetic contact with steel surfaces, making it ideal for both temporary and semi-permanent fixing applications where space is limited.
