• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on the flat circular faces)
• Shape: Low-Profile Compact Disc

Material Description:

Our 8mm x 2mm N52 discs strike the perfect balance between a small horizontal footprint and robust magnetic strength. The 8mm diameter provides ample surface area for adhesive contact, while the 2mm thickness offers enough magnetic volume to project a solid field through thin non-magnetic materials like wood veneers, plastics, or fabrics. These are ideal for hidden cabinetry latches, high-end presentation boxes, and modular 3D-printed assemblies requiring a reliable, space-saving fastening solution.

Handling Advice: CAUTION: These compact magnets carry a surprising snap velocity. Due to their N52 grading, they can snap together quickly from close distances. Because neodymium is inherently brittle, high-impact collisions can chip or crack the plating. Always separate them by sliding the top magnet horizontally off the stack and handle with care during installation.

Warnings and Safety Information:

• CHOKING HAZARD: Small size poses a danger to children and pets. Keep strictly secured.
• Ingestion Warning: Swallowed magnets can attract through internal tissue, causing critical complications. SEEK IMMEDIATE MEDICAL ATTENTION if ingestion occurs.
• Pinch Hazard: Can cause sharp skin pinches or minor blood blisters if handled carelessly in multiples.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.

Applications:

• Concealed magnetic closures for luxury gift boxes, premium binders, and high-end stationery
• Flush-mounted removable panels and access doors for 3D-printed electronic housings
• High-reliability proximity triggers for industrial sensors and small-scale robotics
• Discreet, strong fasteners for high-end leathercraft, wallets, and wearable accessories
• Magnetizing larger components and interchangeable bases for tabletop gaming models
