20mm x 10mm x 2mm (25/32" x 25/64" x 5/64") Neodymium Block Magnet – N52 Grade 

Key Features:

• Dimensions: 20mm Length × 10mm Width × 2mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 5.8 lbs
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized through the 2mm thickness (Poles on the flat 20x10mm faces)
• Shape: Rectangular Block

Material Description:

Our 20x10x2mm N52 blocks are built for professional engineering and high-load DIY projects. The 2mm thickness provides the volume necessary to generate a deep magnetic field, allowing it to "reach" through several millimeters of non-magnetic material. The rectangular geometry ensures the magnet stays firmly aligned and resists rotation when recessed into wood, plastic, or composite materials.

Handling Advice: At nearly 6 lbs of pull force, these magnets are powerful. They will jump toward each other from a significant distance. Always handle one at a time and separate them by sliding the top magnet off the stack to avoid chipping the brittle neodymium core or causing painful skin pinches.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause painful skin pinches or blood blisters. Handle with caution.
• 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 hard drives and magnetic strips.

Applications:

• Heavy-duty magnetic latches for cabinetry, secret doors, and hidden panels
• Industrial proximity sensors and robust magnetic triggers
• High-torque couplings for DIY robotics and high-end RC projects
• Modular mounting systems for workshops and tool organization
• Advanced tabletop gaming (perfect for magnetizing heavy-weight resin kits)
