5mm x 5mm x 1mm (13/64" x 13/64" x 1/32") Neodymium Square Block – N52 Grade 

Key Features:

• Dimensions: 5mm Length × 5mm Width × 1mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 0.73 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
• Magnetization: Axially magnetized through the 1mm thickness (Poles on the large 5x5mm square faces)

Material Description:

Our 5x5x1mm N52 blocks offer a perfect balance of a minimal footprint and substantial magnetic power. The 1mm thickness provides enough magnetic volume to ensure a secure "snap" while remaining thin enough to be recessed into shallow 3D-printed parts, premium leatherwork, or custom joinery. The rectangular geometry ensures the magnet stays perfectly aligned and resists rotation, making it ideal for precision triggers and invisible closures.

Handling Advice: NOTICE: These magnets are powerful and brittle. Due to their thin profile and N52 strength, they can chip if allowed to snap together from a distance. Always separate them by sliding the top magnet off the stack horizontally and handle with care using non-magnetic tools.

Warnings and Safety Information:

• Choking Hazard: Small size is dangerous for children and pets; keep strictly in a secure container.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.
• Ingestion Warning: Swallowing multiple magnets can cause serious internal injury; seek immediate medical help if ingested.
• Electronics: Safe for modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

• Precision sensor triggers for micro-electronics and wearables
• Hidden magnetic latches for premium stationery, wallets, and luxury packaging
• Articulation for 28mm gaming miniatures and high-detail model kits
• Custom reed switch activation in confined industrial electronic prototypes
• Low-profile mounting for micro-LED arrays and lightweight signage
