Product Overview
These 1.26" x 1/4" N45 Neodymium Disc Magnets are designed for applications that require exceptional holding power in a compact disc shape. The large 1.26-inch diameter provides excellent magnetic surface contact, while the thicker 1/4-inch profile generates a stronger magnetic field and greater holding force than thinner disc magnets of the same diameter. With approximately 33 pounds of pull force, these magnets are ideal for demanding industrial, commercial, and workshop applications.
Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets provide significantly greater strength than N42, N40, N38, and N35 grades while offering an excellent balance of performance and value. They are well suited for magnetic fixtures, manufacturing equipment, woodworking, automation systems, magnetic closures, and engineering projects.
Each magnet is protected with a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing outstanding resistance to corrosion, scratches, and chipping while maintaining a smooth, polished metallic finish for long service life.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet made from an alloy of neodymium, iron, and boron. Neodymium magnets are the strongest commercially available permanent magnets and are widely used across industrial, commercial, scientific, and consumer applications.
This magnet is magnetized through its 1/4-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. Disc magnets are commonly used in magnetic fixtures, robotics, manufacturing equipment, woodworking, electronics, product assemblies, and countless custom applications.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1.26" x 1/4" N45 disc magnet provides approximately 33 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force depends on several factors, including:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
For maximum holding performance, use this magnet against a clean, flat, thick steel surface.
Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified for your intended application.
