12mm x 1mm (15/32" x 1/32") Neodymium Disc Magnet – N52 Grade 

Key Features:

• Dimensions: 12mm Diameter × 1mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 1.92 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on the large flat circular faces)
• Shape: Low-Profile Wafer Disc

Material Description:

Our 12x1mm N52 discs are designed for professional engineering and high-end craft projects where vertical space is nearly non-existent. The 12mm diameter provides a large surface area for adhesive bonding, while the 1mm thickness allows the magnet to be hidden behind thin veneers, within luxury stationery, or recessed into shallow 3D-printed cavities. Despite its slim profile, the N52 grade ensures a satisfying and secure "snap" closure every time.

Handling Advice: NOTICE: These magnets are exceptionally thin and brittle. Due to the N52 strength and 1mm thickness, they can snap easily if allowed to jump toward a metal surface. Always separate them by sliding the top magnet off the stack horizontally and handle with care to avoid chipping the brittle core or damaging the nickel plating.

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:

• "Invisible" magnetic closures for luxury greeting cards, wedding invitations, and portfolios
• Hidden latches for ultra-slim jewelry boxes, leather wallets, and high-end packaging
• Precision sensor triggers for micro-electronics and wearable technology
• Flush-mounted removable panels for 3D-printed enclosures
• Low-profile mounting for lightweight graphics and retail signage
