This 4" x 1.5" N48 neodymium disc magnet is designed for applications that require a large magnetic surface and reliable long-term performance. Its wide diameter and substantial thickness provide a strong magnetic profile, making it a practical choice for industrial fixtures, heavy-duty mounting systems, equipment builds, positioning applications, and custom projects where a dependable permanent magnet is needed.

Manufactured from NdFeB (neodymium, iron, and boron) material, this rare earth magnet is built for consistent magnetic performance. The N48 grade provides stronger magnetic output than N45, N42, N40, N38, and N35 grades, with a BrMax rating of 14,200 gauss. This makes it suitable for applications where size, durability, and reliable magnetic performance all matter. The magnet is magnetized through its thickness, with the magnetic poles located on the two flat surfaces. This orientation creates a direct and predictable magnetic connection, allowing the full face of the magnet to be used effectively in mounting and positioning applications.

A Nickel-Copper-Nickel triple-layer coating helps protect the magnet from corrosion, moisture, and everyday wear. This durable finish helps maintain the magnet’s surface quality while supporting long-term use in a variety of environments. Manufactured using controlled production methods and consistent quality standards, this N48 neodymium disc magnet provides a practical balance of size, durability, and dependable magnetic performance for professional, industrial, and custom applications.

Approximate pull force: over 675 lbs
