15mm x 5mm x 1mm (19/32" x 3/16" x 1/32") Neodymium Block Magnet – N52 Grade

Key Features:

• Dimensions: 15mm Length × 5mm Width × 1mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 1.51 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for a durable finish
• Magnetization: Axially magnetized through the 1mm thickness (Poles on the large 15x5mm faces)

Material Description:

Our 15x5x1mm N52 blocks are designed for professional engineering and high-end craft projects that require a long, narrow magnetic footprint. The 15mm length provides excellent leverage for closures, while the rectangular shape ensures the magnet stays perfectly aligned when recessed into wood, plastic, or leather. This "strip" profile is the top choice for hidden latches in high-end stationery and presentation boxes.

Handling Advice: These magnets are powerful and brittle. Due to their elongated shape and 1mm profile, they can snap if allowed to jump toward metal surfaces. Always separate them by sliding the top magnet off the stack horizontally and handle with a steady grip to avoid chipping the brittle neodymium core.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause minor skin pinches. Handle with care.
• 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.
• Electronics: Safe for modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

• Hidden magnetic latches for leather portfolios, premium wallets, and luxury bags
• Invisible edge-mounting for graphics and signage in museum displays
• Precision sensor triggers for industrial electronic prototypes
• Custom joinery and "secret" compartment latches in fine woodworking
• 3D-printed removable covers and slim battery compartments
