25mm x 10mm (63/64" x 25/64") Neodymium Disc Magnet – N52 Grade

Key Features:

• Dimensions: 25mm Diameter × 10mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 46.8 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on the flat circular faces)
• Surface Gauss: Approx. 5,320 Gauss

Material Description:

Our 25x10mm N52 discs are engineered for heavy-duty applications where maximum magnetic reach is essential. The 10mm thickness creates a massive magnetic volume that can penetrate through thick non-magnetic barriers like heavy structural timber, thick industrial plastics, or composite housings. These are the premier choice for heavy-duty hidden latches, industrial magnetic separators, and securing heavy equipment in high-vibration environments.

Handling Advice: CRITICAL DANGER: These magnets are extremely powerful and dangerous. With nearly 50 lbs of pull force, two magnets will jump together from several inches away with enough speed to shatter the core or cause serious injury to fingers (including broken bones or severe crushing). Always handle one at a time and use non-magnetic spacers. NEVER let them snap together or onto steel surfaces without controlled mechanical assistance.

Warnings and Safety Information:

• Crush Hazard: High risk of serious injury. Handle with industrial-strength focus and protective gear.
• Choking Hazard: Keep strictly away from children and pets.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.
• Electronics: Keep well away from hard drives, credit cards, and sensitive electronic testing equipment.

Applications:

• Heavy-duty magnetic stirrers for industrial-scale high-viscosity chemistry
• Industrial-strength tool organization and heavy equipment mounting in workshops
• Magnetic separation systems for removing ferrous contaminants from bulk materials
• High-torque magnetic couplers and rotors for professional robotics or wind turbines
• Heavy-duty removable panels for automotive, aerospace, or industrial housing
