25mm x 25mm x 2mm Neodymium Square Block – N52 Grade

Key Features:

• Dimensions: 25mm Length × 25mm Width × 2mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52
• Pull Force: Approx. 11.1 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on the large 25x25mm flat faces)
• Shape: Wide Square Block

Material Description:

Our 25mm N52 square blocks are engineered for maximum stability and strength. The broad 1-inch footprint provides a massive surface area for adhesive bonding and ensures a non-slip grip on ferrous surfaces. Despite being only 2mm thick, the high-grade N52 material creates a deep magnetic field that "reaches" through thin non-magnetic barriers. This makes them perfect for hidden structural latches and high-end retail displays.

Handling Advice: DANGER: These magnets are extremely powerful. With over 16 lbs of pull force, they can snap together with enough speed to shatter the ceramic core or cause serious skin pinches. Always handle one at a time and use a sliding motion to separate them. Use non-magnetic tools to maintain the finish and avoid accidents.

Warnings and Safety Information:

• Crush Hazard: Can cause painful skin pinches or blood blisters. Handle with a firm, steady grip.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.
• Brittleness: Neodymium is a ceramic; high-impact collisions will cause shattering.
• Electronics: Safe for most modern devices at a distance, but avoid direct contact with hard drives and magnetic strips.

Applications:

• Heavy-duty magnetic mounting for signage, graphics, and museum displays
• Concealed latches for secret doors, panels, and Murphy beds
• Industrial-strength jigs, fixtures, and non-slip workbench clamps
• Precision 3D-printed removable panels and heavy-load enclosures
• High-torque magnetic couplings for industrial robotics and prototypes
