Super Magnet Store offers premium-quality N52 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets provide maximum magnetic strength, dependable performance, and long-term durability for industrial, commercial, and engineering applications.

This N52 neodymium block magnet measures 1.5" x 3/4" x 1/4" and generates approximately 33 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N50, N48, N45, N42, N40, N38, and N35 grades.

The durable Nickel-Copper-Nickel triple-layer coating provides superior corrosion resistance and wear protection. Manufactured under ISO-certified quality standards, this magnet offers consistent magnetic strength and reliable performance in demanding environments.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide exceptional holding force and a large contact surface area, making them ideal for industrial equipment, manufacturing fixtures, engineering projects, robotics, automation systems, cabinetry, and custom magnetic assemblies.

How Strong Is This Magnet?

This N52 neodymium block magnet generates approximately 33 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a Br Max rating of 14,800 Gauss, it delivers outstanding magnetic performance in a compact block design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 33 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, steel thickness, and application design.

Is N52 stronger than N50?

Yes. N52 magnets provide greater magnetic energy and holding force than N50 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

Can it rust?

The protective nickel coating helps resist corrosion; however, moisture exposure and coating damage can eventually result in rust.

What direction is it magnetized?

This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 1.5" x 3/4" faces.
