5mm (13/64") Neodymium Sphere Magnets – N52 Grade

Key Features:

Diameter: 5mm (Approx. 13/64")
Precision Tolerance: ±0.05mm
Magnet Grade: N52
Pull Force: Approx. 1.26 lbs
Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
Magnetization: Axially magnetized (Poles on opposite sides of the sphere)

Material Description:

Our 5mm N52 spheres are designed for high-stress applications that require a robust magnetic bond. Because they are spherical, they naturally rotate to align their poles, creating an instant and secure connection from any angle. This "self-aligning" property, combined with the extreme power of N52 neodymium, makes these spheres the premier choice for articulating heavy joints in high-end robotics, large-scale custom figurines, and complex architectural models.

Handling Advice: DANGER: These spheres have considerable "jump" distance. Because they are spherical, they roll quickly and can snap together with enough force to shatter the brittle ceramic core. Always handle them with a firm grip and avoid letting them slam into one another or ferrous surfaces. We recommend working on a non-magnetic rubber mat to prevent runaway magnets.

Warnings and Safety Information:

CHOKING & INGESTION HAZARD: Extremely dangerous if swallowed. Keep strictly away from children and pets.
Ingestion Warning: Swallowed magnets can attract through intestinal walls, causing life-threatening injury. SEEK IMMEDIATE MEDICAL ATTENTION if ingestion occurs.
Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.
Electronics: Safe for modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

Heavy-duty ball-and-socket joints for large-scale action figures and robotic prototypes
