Product Description The 12mm x 9mm x 6mm Neodymium Block Magnet is a compact yet incredibly powerful rare-earth magnet designed for high-precision engineering. Its rectangular geometry provides stable flat surfaces for mounting, while the N35 grade material ensures a high magnetic flux density. Each block is finished with a triple-layer Ni-Cu-Ni coating, providing a polished look and essential protection against the oxidation typical of raw neodymium materials.

Key Features

  • High Power-to-Size Ratio: Delivers a strong vertical pull force despite its small 12x9mm footprint.

  • Axial Magnetization: The poles are located on the two largest flat surfaces (12mm x 9mm), ensuring maximum surface contact and grip.

  • Triple-Layer Plating: High-quality nickel-copper-nickel coating offers excellent durability and corrosion resistance.

  • Precision Edges: Clean rectangular corners allow for easy integration into CNC-milled slots or 3D-printed assemblies.

  • Solid-State Performance: No moving parts; provides a permanent and reliable magnetic field for the life of your project.

Technical Details

  • Material: Sintered NdFeB.

  • Max Operating Temp: 80°C (176°F).

  • Dimensional Tolerance: ±0.1mm.

Prototyping and Engineering Tips from Robogears

  • Precision Latching: This specific size is a favourite for battery compartment covers and robot panels. The 6mm thickness gives it enough "meat" to be handled easily but is slim enough to stay low-profile.

  • Safe Separation: To avoid chipping, never try to pull these magnets apart. Instead, slide the top magnet sideways off the stack.

  • Fragility Alert: Neodymium is a brittle material. If two magnets snap together from a distance, the impact energy can cause them to shatter or chip. Always maintain a firm grip and bring them together slowly.

  • Adhesive Advice: For a permanent fix, use a thick gel-based cyanoacrylate or a two-part epoxy. Scuffing the smooth nickel surface slightly with fine sandpaper can drastically improve the bond strength.

Package Includes

  • 1 x 12mm x 9mm x 6mm Neodymium Block Magnet
