N52 Neodymium Magnets 1 in x 1 in x 1/4 in Rare Earth Block

N52 Neodymium Magnets 1 in x 1 in x 1/4 in Block – High-Strength Rare Earth Magnet for Secure Mounting and Precision Applications
Engineered for maximum holding force in a compact form, this N52 neodymium block magnet (1 inch x 1 inch x 1/4 inch) offers superior strength for demanding applications. Its square face and low-profile thickness make it ideal for secure mounting, high-force closures, and precision assemblies where power and size efficiency are critical.

Key Features:

  • Compact Rare Earth Block Magnet: 1-inch x 1-inch face ensures stable surface contact, while the 1/4-inch thickness allows for low-profile integration in assemblies.
  • Ultra-Strong N52 Grade: Stronger than N50, N48, and N45 grades, with BrMax of 14,400 gauss, delivering maximum magnetic force for its size.
  • Estimated Pull Force: Rated to hold over 36 lbs under ideal conditions only (flat, clean, uncoated steel surface). Real-world results may vary depending on surface contact, alignment, and environment.
  • Typical Heat Rating: Max operating temperature is 80°C (176°F). Exceeding this limit may result in permanent loss of magnet strength.
  • Triple Coated: Nickel-Copper-Nickel plating for durability and corrosion resistance, extending lifespan in shop, lab, or outdoor environments.
  • Magnetized Through Thickness: North and south poles are on the 1-inch faces, ensuring optimal alignment and secure attachment in your projects.

Frequently Asked Questions

How strong is this N52 neodymium magnet compared to other grades?
N52 is the strongest grade of neodymium magnets available for commercial use, providing higher magnetic strength than N35, N42, N45, N48, and N50. This 1" x 1" x 1/4" block magnet offers over 36 lbs of pull force in laboratory settings, measured on flat, unpainted steel. Real-world holding force may be lower depending on surface, air gaps, or misalignment.

What is this magnet coated with?
This neodymium magnet is coated with a triple layer of Nickel-Copper-Nickel, providing excellent durability and corrosion resistance for use in workshops, labs, or light outdoor environments.

Which applications is this magnet best suited for?
This magnet is ideal for heavy-duty magnetic closures, robotics and CNC fixtures, precision instrument mounting, sensor arrays, secure cabinetry latches, and educational or engineering projects requiring maximum holding force in a compact size.

Are there any safety considerations when handling this magnet?
Yes. Neodymium magnets are extremely powerful and can snap together unexpectedly, potentially causing pinched fingers or chipping. Always handle with care, keep away from children, pacemakers, and sensitive electronics, and review magnet safety guidelines before use.


Safety Note:

Always handle high-strength magnets with care and review magnet safety guidelines before use.
