• Pull Force: Approx. 0.45 LB
• Magnet Grade: N52 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for durability
• Magnetization: Axially magnetized (Poles on the flat 4mm faces)
• Shape: Thin Disc

Material Description:

Our 4x1mm N52 discs are designed for applications requiring a "flush" finish. At just 1mm thick, these magnets are thin enough to be hidden behind cardstock or recessed into a shallow 4mm drill hole. The N52 grade ensures that despite its thinness, it provides a snappy and reliable magnetic connection.

Handling Note: Ultra-thin magnets are extremely fragile. They should never be allowed to snap together from a distance. Always slide them apart to avoid cracking the brittle neodymium core.

Warnings and Safety Information:

• Choking Hazard: Small size is dangerous for children and pets. Keep strictly in a secure container.
• Handling: Use a sliding motion to separate; avoid using metal tools that could strike and shatter the magnet.
• Medical: Keep away from pacemakers and sensitive medical implants.
• Storage: Keep away from credit cards and magnetic strips.

Applications:

• Magnetic closures for premium packaging and folders
• Tabletop miniature basing (for 28mm-32mm scale figures)
• Small jewelry clasps and craft projects
• Hidden magnetic latches for balsa wood or plastic models
• Sensor triggers in space-constrained electronics
