Product Description The 20x12x6mm Neodymium Block Magnet is an exceptionally powerful rare-earth magnet designed for high-performance industrial and DIY applications. Its rectangular "block" shape offers a large, flat surface area for a massive holding force, while the 6mm thickness provides a deep magnetic reach. Each magnet is protected by a premium Ni-Cu-Ni triple-layer coating, ensuring a smooth, corrosion-resistant finish that looks professional in any assembly.

Key Features

Extreme Pull Force: N35 grade neodymium offers a superior strength-to-size ratio compared to standard ceramic magnets.
Precision Rectangular Geometry: The flat 20x12mm faces are perfect for flush-mounting or surface bonding.
Triple-Layer Protection: Nickel-Copper-Nickel plating prevents the brittle neodymium core from oxidizing or rusting.
Axial Magnetization: The North and South poles are located on the largest flat surfaces (300mm² area), maximizing the effective "grip."
Industrial Versatility: Ideal for heavy-duty latches, magnetic separation, robotics, and high-end cabinetry.

Technical Details

Material: Sintered Neodymium-Iron-Boron.
Max Operating Temp: 80°C.
Tolerance: ±0.1mm.

Prototyping and Engineering Tips from Robogears

The "Leverage" Secret: Because these magnets are so strong, they are very difficult to pull apart vertically. Always slide them sideways to separate them.
Secure Mounting: For permanent installations, use a high-bond epoxy. The smooth nickel coating can be slippery, so lightly scuffing the magnet's surface with sandpaper can improve glue adhesion.
Impact Warning: Neodymium is essentially a "metallic ceramic" and is extremely brittle. If you allow two blocks to snap together from a distance, they will likely shatter. Always handle with a firm grip and use a non-magnetic spacer (like wood or plastic) when storing them.
DIY Tool Storage: These blocks are powerful enough to hold heavy wrenches or pliers. Glue a row of them inside a tool cabinet to create a high-strength magnetic organizer.
