Key Specifications

  • Pull Force: 13.1 lbs
  • Dimensions: 20mm × 20mm × 3mm (25/32" × 25/32" × 1/8")
  • Material: Neodymium (NdFeB) - The world's strongest permanent magnet

Product Description

This powerful N52 neodymium magnet block delivers exceptional holding strength in a compact design. Made from a rare earth alloy of neodymium, iron, and boron, it represents the pinnacle of permanent magnet technology. Despite its incredible 13.1 lb pull force, the magnet is constructed from brittle ceramic-like material that requires careful handling to prevent damage.

The magnet features a protective nickel-copper-nickel coating to prevent rust and corrosion, ensuring reliable performance over time.
