• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 1.8 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on two opposite flat faces)
• Surface Gauss: Approx. 5,200 Gauss

Material Description:

Our 4mm N52 cubes are engineered for applications that require significant 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 magnetic flux than a 4mm disc. These are highly sought after for industrial-grade sensor triggers, micro-robotics, and advanced tabletop gaming miniatures where a strong "snap" is required.

Handling Advice: NOTICE: These magnets are small but surprisingly strong. Due to their sharp corners and N52 grade, they can chip if allowed to snap together with force. Always separate them by sliding the top magnet off the stack horizontally and handle with a firm grip to avoid snapping or shattering the brittle core.

Warnings and Safety Information:

• Choking Hazard: Small size is dangerous for children and pets. Keep strictly in a secure container.
• 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 care.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.

Applications:

• Heavy-duty 3D-printed latches and removable compartments
• High-performance sensor triggers for industrial electronics and robotics
• Articulation for gaming miniatures (ideal for heavy weapon swaps or large kits)
• Modular mounting systems for small tools and workshop organization
• Custom reed switch activation in confined industrial spaces
