Product Description The 12mm x 7mm x 18mm Neodymium Block Magnet is a specialized heavy-duty magnet characterized by its significant 18mm thickness. This "tall" block design creates a concentrated magnetic field with a deeper reach compared to flatter magnets. Each unit is made from high-grade N35 neodymium and protected by a Ni-Cu-Ni triple-layer coating, ensuring a smooth, corrosion-resistant finish for professional and industrial applications.

Key Features

  • Massive Magnetic Depth: The 18mm thickness generates a concentrated magnetic field that extends further through non-magnetic materials.

  • High Pull Force: N35 grade material provides an exceptional power-to-weight ratio for industrial-strength holding.

  • Precision Geometry: Clean rectangular edges make it easy to mount into custom drilled slots or 3D-printed housings.

  • Durable Protection: Triple nickel plating prevents the brittle core from oxidizing and adds a polished silver look.

  • Axial Alignment: Magnetized through the 18mm dimension, placing the poles on the 12x7mm faces for maximum grip.

Technical Details

  • Material: Sintered Neodymium-Iron-Boron.

  • Max Operating Temp: 80°C.

  • Dimensional Tolerance: ±0.1mm.

Prototyping and Engineering Tips from Robogears

  • Deep-Reach Applications: Because this magnet is 18mm thick, it is perfect for situations where the magnet must act through thick barriers, such as wooden panels or heavy-duty plastic robot shells.

  • Safe Handling: These magnets are extremely difficult to pull apart directly. Always slide them sideways to break the magnetic bond.

  • Fragility Alert: Neodymium is essentially a metallic ceramic. If you allow two blocks to "slam" together, they will likely shatter or chip. Always handle with a firm grip.

  • Mounting Advice: For permanent bonds, use a high-strength epoxy. Lightly scuffing the smooth nickel coating with sandpaper can help improve glue adhesion.

Package Includes

  • 1 x 12mm x 7mm x 18mm Neodymium Block Magnet
