12mm x 0.5mm (15/32" x 1/64") Neodymium Disc Magnet – N52 Grade | Ultra-Thin Stealth Wafer

Key Features:

• Dimensions: 12mm Diameter × 0.5mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 0.96 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized through the 0.5mm thickness (Poles on the large flat faces)

Material Description:

Our 12x0.5mm N52 discs are engineered for the most space-constrained applications. The ultra-thin 0.5mm profile allows these magnets to be hidden behind thin veneers, within premium cardstock, or between layers of fabric without creating a visible bulge. The 12mm width provides an expansive surface area for adhesive bonding, ensuring the magnet stays securely in place even in high-cycle use cases like luxury packaging or wearable tech.

Handling Advice: EXTREME CARE REQUIRED: These magnets are exceptionally fragile. Due to the 0.5mm thickness and the brittle nature of neodymium, 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 horizontally.

Warnings and Safety Information:

• Fragility Hazard: These will shatter if dropped or allowed to snap together. Handle like thin glass.
• 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 at all times.
• Ingestion Warning: Swallowing multiple magnets can lead to severe internal complications.

Applications:

• "Invisible" magnetic closures for luxury greeting cards, wedding invitations, and portfolios
• Ultra-slim proximity sensors and Hall effect triggers in mobile devices and tablets
• Low-profile mounting for lightweight graphics and retail signage
• Seam-sealing and invisible fasteners for delicate textile and garment applications
• Precision shimming and leveling in micro-mechanical systems
