Precision Tolerance: ±0.05mm
Magnet Grade: N52
Pull Force: Approx. 6.98 lbs
Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
Magnetization: Axially magnetized (Poles on the flat circular faces)
Surface Gauss: Approx. 2,528 Gauss

Material Description:

Our 18x2mm N52 discs are designed for professional engineering and structural applications that require a wide, stable bond without adding significant bulk. The 18mm diameter provides an expansive surface area for adhesive contact, ensuring the magnet stays securely anchored even under shear stress. At 2mm thick, these magnets are ideal for "invisible" closures behind wood veneers or plastic panels, providing a robust "snap" for high-end cabinetry and modular displays.

Handling Advice: NOTICE: These large-diameter magnets carry significant snap velocity. With over 5 lbs of pull force and a wide surface area, they can jump toward each other or ferrous surfaces with enough speed to shatter the brittle core. Always separate them by sliding the top magnet off the stack horizontally and avoid high-impact collisions.

Warnings and Safety Information:

Pinch Hazard: Strong enough to cause painful skin pinches or blood blisters. Handle with a steady, firm grip.
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 at all times.
Electronics: Safe for modern devices at a distance, but avoid direct contact with magnetic storage media.
