Neodymium Disc Magnets N52 2 in x 0.25 in – High-Strength Rare Earth Magnets

Engineered for maximum holding force and reliability, these N52 disc magnets deliver a powerful magnetic performance for demanding industrial, engineering, and DIY applications. Featuring a 2-inch diameter with a low-profile 0.25-inch thickness, these rare earth magnets combine strength and versatility in a compact form factor.

Key Features:

• High-Strength N52 Grade: Stronger than N50, N48, N45, N42, and lower grades, these magnets provide a BrMax of approximately 14,800 gauss for powerful, consistent magnetic force in advanced applications.
• Precision Disc Design: Each magnet measures 2 inches in diameter and 0.25 inches thick, offering a large contact area for secure holding while maintaining a manageable weight for versatile use.
• Triple Coated for Durability: Nickel-Copper-Nickel triple-layer coating ensures maximum corrosion resistance and long-term protection, critical for use in industrial and outdoor environments.
• Magnetized Through Thickness: North and south poles are located on the flat faces of the disc, allowing stable alignment and reliable performance in assemblies.
• NdFeB Patent Licensed: Manufactured to the highest quality standards, ensuring consistent performance with licensed NdFeB technology.
• Powerful Pull Force: Approximate 77 lbs under ideal conditions. Actual pull may be lower depending on surface type, thickness, and alignment.
• Maximum Operating Temperature: Rated for continuous use up to 80°C (176°F). Higher temperatures may permanently reduce magnetic strength.

Technical Specifications

Frequently Asked Questions

What makes N52 grade magnets the best choice?
N52 is the strongest commercially available grade, offering significantly higher holding power than N48, N45, and lower grades, making it ideal for high-force applications.

Are these magnets coated for protection?
Yes, they have a Nickel-Copper-Nickel triple coating, providing excellent corrosion resistance and long-lasting durability.

How are these magnets magnetized?
They are magnetized through the thickness, with north and south poles on the flat surfaces, ensuring optimal alignment and holding performance in your projects.

Will this magnet always hold 77 lbs?
No. The pull force is measured under ideal conditions. Real-world holding strength may be lower depending on the contact surface, material, and alignment.

Can I use these magnets for renewable energy and engineering prototypes?
Absolutely. These high-strength discs are ideal for custom wind or hydro turbine assemblies, generator prototypes, and other engineering projects requiring powerful magnetic fields.

Safety Note:

Neodymium magnets are very powerful and may attract each other suddenly, risking pinched fingers or chipping. Handle carefully, and keep away from children, pacemakers, and sensitive electronics.
