This 4" x 2" N42 neodymium disc magnet is designed for industrial applications that require a large, reliable magnetic component with consistent performance. Its wide diameter and full 2-inch thickness provide a substantial magnetic profile, making it suitable for heavy-duty fixtures, machinery, fabrication projects, positioning systems, and custom assemblies where dependable magnetic holding is important.

Made from neodymium, iron, and boron, this NdFeB rare earth magnet is a permanent magnet built to maintain its magnetic properties over time. The N42 grade provides stronger magnetic performance than N40, N38, and N35 grades, with a BrMax rating of 13,200 gauss. This combination of size and magnetic output makes it a practical choice for demanding industrial and engineering applications. The magnet is magnetized through its thickness, with the magnetic poles located on the two flat surfaces. This orientation allows for a direct and predictable magnetic connection, making the magnet easier to incorporate into mounting, clamping, and positioning designs.

A Nickel-Copper-Nickel triple-layer coating helps protect the magnet from corrosion, moisture, and everyday wear. This durable finish helps preserve the magnet’s surface condition and supports reliable performance in a variety of working environments. Manufactured using modern production methods and consistent quality standards, this N42 neodymium industrial magnet provides a durable and dependable solution for applications where size, strength, and long-term reliability are important.
