5mm x 5mm x 0.5mm (13/64" x 1/64") Neodymium Square Block – N52 Grade 

Key Features:

• Dimensions: 5mm Length × 5mm Width × 0.5mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 0.35 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
• Magnetization: Axially magnetized through the 0.5mm thickness (Poles on the large 5x5mm faces)

Material Description:

Our 5x5x0.5mm N52 blocks are engineered for the most space-constrained applications. The ultra-thin 0.5mm profile allows these magnets to be placed behind thin veneers, within tight electronic housings, or between layers of fabric and paper without creating a visible bulge. The square geometry provides better stability and surface area for adhesive bonding than a circular disc of the same thickness.

Handling Advice: EXTREME CARE REQUIRED: These magnets are exceptionally fragile. Due to the 0.5mm thickness, they can snap or shatter with very little pressure. Never bend them or allow them to snap together from a distance. Always separate them by gently sliding them apart and handle them with non-magnetic precision tweezers.

Warnings and Safety Information:

• Fragility Hazard: These will break if dropped or snapped together. Handle like glass.
• Choking Hazard: Extremely dangerous for children and pets due to their tiny, easily ingestible size.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.
• Ingestion Warning: Swallowing multiple magnets can lead to severe internal complications.

Applications:

• Ultra-slim proximity sensors and Hall effect triggers in mobile devices
• "Invisible" magnetic closures for premium stationery, greeting cards, and luxury packaging
• Precision shimming and leveling in micro-mechanical systems
• Seam-sealing for delicate textile applications and wearable tech
• Low-profile mounting for micro-LED arrays and lightweight graphics
