15mm x 15mm x 0.5mm (19/32" x 19/32" x 1/64") Neodymium Square Block – N52 Grade 

Key Features:

• Dimensions: 15mm Length × 15mm Width × 0.5mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: approx. 1.42 lbs
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on the large 15x15mm flat faces)
• Shape: Ultra-Thin Wide Square Block

Material Description:

Our 15x15x0.5mm N52 blocks are designed for applications where thickness is critically limited but a large contact area is required. The 15mm square footprint allows for a secure, non-slip hold, making it ideal for securing heavy cardstock, menu flaps, or hidden panels in high-end presentation boxes. Its geometric shape ensures it won't rotate or shift when embedded into precision-cut recesses.

Handling Note: Due to the extreme surface area and 0.5mm profile, these magnets are exceptionally fragile. They can snap easily if allowed to jump toward metal surfaces. Always separate them by sliding the top magnet off the stack horizontally and handle with extreme 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.
• Fragility: Neodymium is a ceramic; wide, thin blocks can shatter upon impact. Handle with extreme care.
• Electronics: Safe for modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

• High-end magnetic closures for luxury portfolios, menu covers, and presentation boxes
• Stealth mounting for graphics and signage in museum and gallery displays
• Hidden latches for premium furniture veneers and high-end cabinetry
• Precision sensors in ultra-slim industrial electronic prototypes
• Architectural scale modeling where a wide, flat magnetic bond is required
