6mm (15/64") Neodymium Sphere Magnets – N52 Grade 

Key Features:

• Diameter: 6mm (Approx. 15/64" or 1/4")
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 1.93 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on opposite sides of the sphere)

Material Description:

Our 6mm N52 spheres are engineered for professional applications where maximum magnetic strength is required in a spherical form factor. The N52 grade provides a deep, concentrated magnetic field that allows these spheres to securely "snap" together or hold components through thicker non-magnetic layers. Their ability to rotate freely to find their own poles makes them indispensable for creating robust ball-and-socket joints in robotics, high-end articulated models, and advanced industrial prototypes.

Handling Advice: DANGER: These spheres pack a serious punch for their size. Because they are spherical and N52 grade, they will jump toward each other from several inches away. High-impact collisions can easily cause the brittle neodymium core to shatter or chip. Always handle with a firm grip and work on a non-magnetic mat to prevent runaway magnets and impact damage.

Warnings and Safety Information:

• CHOKING & INGESTION HAZARD: Extremely dangerous if swallowed. These are a major safety risk for children and pets.
• Ingestion Warning: Swallowed magnets can attract through intestinal walls, causing life-threatening injury. KEEP OUT OF REACH OF CHILDREN AND PETS.
• Pinch Hazard: Strong enough to cause painful skin pinches or small blood blisters.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.

Applications:

• High-load ball-and-socket joints for custom action figures and robotic prototypes
• Industrial-grade proximity sensors and high-accuracy magnetic triggers
• Precision magnetic bearings for micro-mechanical systems
• Advanced 3D-modeling and architectural structural prototypes
• Modular mounting for wearable tech, heavy props, and high-end fashion closures
