• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 0.9 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on two opposite flat faces)
• Surface Gauss: Approx. 4,800 Gauss

Material Description:

Our 3mm N52 cubes are built for applications that require high magnetic strength in a symmetrical, non-rolling format. The cubic geometry allows for easy orientation in 3D-printed parts and CNC-machined recesses, providing more "meat" and magnetic flux than a 3mm disc. These are highly sought after for precision sensor triggers, micro-robotics, and advanced tabletop gaming miniatures.

Handling Advice: NOTICE: These magnets are small but surprisingly strong. Due to their sharp corners and N52 strength, they can chip if allowed to snap together with force. Always separate them by sliding the top magnet off the stack horizontally and use non-magnetic tools for precise installation.

Warnings and Safety Information:

• Choking Hazard: EXTREMELY DANGEROUS for children and pets. Their size makes them easily ingestible.
• Ingestion Warning: Swallowing multiple magnets can cause serious internal injury. Seek immediate medical help if ingested.
• Pinch Hazard: Strong enough to cause minor skin pinches. Handle with a steady grip.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.

Applications:

• Precision 3D-printed latches and removable compartments
• High-performance sensor triggers for micro-electronics and wearables
• Articulation for 28mm and 32mm gaming miniatures (ideal for heavy weapon swaps)
• Micro-robotics and miniature electromagnetic actuator components
• Custom reed switch activation in confined industrial spaces
