Material Description:

Our 25x2mm N52 discs are designed for professional engineering and structural applications that require an expansive magnetic footprint without adding bulk. The 25mm diameter provides superior resistance to shear forces and an incredible amount of surface area for adhesive bonding. At just 2mm thick, these magnets are ideal for "invisible" closures behind wood veneers or plastic panels, providing a massive 10.5 lb "snap" for high-end furniture, modular retail displays, and heavy-duty 3D-printed assemblies.

Handling Advice: DANGER: These large-diameter magnets carry significant snap velocity. With over 10 lbs of pull force and a wide surface area, they can jump toward each other or ferrous surfaces from a distance with enough speed to shatter the brittle core or cause painful skin pinches. Always separate them by sliding the top magnet off the stack horizontally and handle with a firm, steady grip.

Warnings and Safety Information:

Pinch Hazard: Strong enough to cause blood blisters or painful skin pinches. Handle with caution.
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:

Concealed magnetic latches for heavy secret doors, panels, and luxury cabinetry
Heavy-duty 3D-printed enclosures and removable structural partitions
Secure mounting for heavy retail signage, lighting fixtures, and industrial graphics
Magnetic couplers for professional robotics and mechanical prototypes
High-performance proximity sensors requiring a wide target area and robust field
