30mm x 10mm (1-3/16" x 25/64") Neodymium Disc Magnet – N52 Grade 

Key Features:

• Dimensions: 30mm Diameter × 10mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 58.4 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
• Magnetization: Axially magnetized (Poles on the flat circular faces)
• Surface Gauss: Approx. 5,200 Gauss

Material Description:

Our 30x10mm N52 discs are engineered for applications where maximum magnetic reach and extreme holding force are mandatory. The 10mm thickness creates a massive magnetic volume that can penetrate through thick non-magnetic barriers like structural timber, thick industrial plastics, or composite housings. These are the premier choice for heavy-duty hidden structural latches, industrial magnetic separators, and securing heavy equipment in high-vibration environments.

Handling Advice: CRITICAL DANGER: These magnets are extremely powerful and hazardous. With nearly 70 lbs of pull force, two magnets will jump together from a significant distance with enough speed to shatter the brittle core or cause severe injury to fingers, including crushing or broken bones. Always handle one at a time and use thick 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 and mixing
• Industrial-strength tool organization and heavy equipment mounting in professional workshops
• Magnetic separation systems for removing ferrous contaminants from high-volume bulk materials
• High-torque magnetic couplers and rotors for professional robotics or renewable energy turbines
• Heavy-duty removable panels for automotive, aerospace, or industrial housing
