Product Overview

These 1.5" x 1/16" N45 Neodymium Disc Magnets combine a large magnetic surface area with an ultra-thin profile, making them ideal for applications where a low-profile magnet is required without sacrificing holding performance. The 1.5-inch diameter provides broad magnetic coverage, while the 1/16-inch thickness allows for nearly flush installations. Under ideal conditions, these magnets produce approximately 9 pounds of pull force.

Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these magnets offer stronger magnetic performance than N42, N40, N38, and N35 grades. They are well suited for product assemblies, retail displays, cabinet closures, electronics, educational projects, and countless custom applications where reliable magnetic strength is needed.

Each magnet is finished with a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished appearance. Manufactured in ISO-certified facilities, these magnets deliver dependable quality and long service life.

What Is a Neodymium Disc Magnet?

A neodymium disc magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet manufactured from an alloy of neodymium, iron, and boron. Neodymium magnets are the strongest commercially available permanent magnets and are widely used throughout industrial, commercial, scientific, and consumer applications.

This magnet is magnetized through its 1/16-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. Disc magnets are valued for their compact design, wide contact surface, and strong holding force, making them ideal for magnetic mounting, product assemblies, displays, electronics, cabinetry, and engineering projects.

Neodymium magnets are also known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.

How Strong Is This Magnet?

This 1.5" x 1/16" N45 disc magnet provides approximately 9 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.

Common Questions About This Magnet

What is the pull force?

This magnet provides approximately 9 pounds of pull force under ideal testing conditions.

Is N45 stronger than N35 magnets?

Yes. N45 provides substantially greater magnetic strength and holding power than N35 magnets of the same dimensions.

Can it rust?

The Nickel-Copper-Nickel triple-layer coating helps protect against corrosion. If the coating becomes damaged and moisture reaches the magnet, corrosion may occur over time.

Can it be used outdoors?

Yes. However, additional sealing is recommended for prolonged outdoor exposure or marine environments.

What direction is it magnetized?

This magnet is magnetized through its 1/16-inch thickness (axially magnetized), with the north and south poles located on the two flat circular faces.
