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

Key Features:

• Dimensions: 15mm Length × 15mm Width × 1mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 2.84 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for superior durability
• Magnetization: Axially magnetized through the 1mm thickness (Poles on the flat square faces)
• Shape: Thin Square Block

Material Description:

Our 15x15x1mm N52 blocks offer a perfect middle ground for engineering and craft projects. The 15mm square footprint provides a stable, non-slip base for adhesives, while the 1mm thickness provides a much deeper magnetic "reach" than ultra-thin alternatives. These are ideal for flush-mounting into CNC-machined pockets or 3D-printed recesses where a professional, "hidden" look is required.

Handling Advice: N52 material is exceptionally brittle. Because of the sharp corners on square blocks, they are prone to chipping if allowed to snap together. Always separate them by sliding the top magnet off the stack rather than lifting, and handle with care using non-magnetic tools to maintain the nickel finish.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause minor skin pinches. Handle with a steady grip.
• 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 most modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

• Precision 3D-printed removable panels and battery covers
• Magnetic latches for high-end cabinetry, display boxes, and furniture
• Industrial-strength hidden closures for luxury folders and binders
• Modular "tiling" for magnetic tool boards and display systems
• Advanced tabletop gaming (ideal for magnetizing large resin bases)
