These 1/2" x 1/8" N52 neodymium disc magnets are built for maximum strength and long-lasting performance. The wide 1/2" diameter provides excellent surface contact for a secure grip, while the 1/8" thickness adds depth and stability—delivering a noticeably stronger hold than thinner discs.

Made from premium N52 grade rare earth neodymium, these magnets offer one of the highest levels of magnetic force available. They provide a firm, consistent hold across a wide range of applications, from everyday organization to more demanding projects. Each magnet is finished with a durable nickel coating that helps protect against corrosion and wear while maintaining a clean, polished appearance.

Common Applications:

  • Magnetic closures for electronics and small enclosures
  • Sensor arrays and precision alignment systems
  • Robotics and hobbyist projects requiring small, strong magnets
  • Educational kits and science experiments
  • Lightweight industrial holding and retrieval tools

Frequently Asked Questions (FAQ)

How strong is this N52 compared to others?
N52 is the strongest standard grade for neodymium magnets, providing maximum pull force in the smallest possible size.
What affects real-world holding strength?The actual pull depends on metal thickness, contact surface smoothness, angle, and coatings like paint or powder.

Can I use this magnet for electronics and sensors?
Yes, but ensure clearances are adequate to prevent interference or accidental attraction to sensitive components.

How should I mount this magnet?
Use epoxy adhesives or secure in a recessed fixture for flush mounting. Handle with care to avoid pinching fingers or chipping the magnet during handling.

Is this magnet resistant to corrosion?
Yes, the Nickel-Copper-Nickel coating provides excellent corrosion resistance for most indoor and controlled environments.
