8mm (5/16") Neodymium Sphere Magnets – N35 Grade

Key Features:

Diameter: 8mm (Approx. 5/16")
Precision Tolerance: ±0.05mm
Magnet Grade: N35
Pull Force: Approx. 2.14 lbs
Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
Magnetization: Axially magnetized (Poles on opposite sides of the sphere)

Material Description:

Our 8mm N35 spheres are built for structural and interactive applications that require a larger spherical footprint. The 8mm diameter provides excellent grip and visibility, making them ideal for architectural models, industrial prototyping, and custom joint articulation in large-scale figurines. These spheres naturally align their poles upon contact, creating a "self-centering" joint that provides a satisfying and secure connection every time.

Handling Advice: NOTICE: These magnets carry significant mass. Due to their 8mm size and magnetic strength, they can roll quickly and snap together with force. While N35 is more durable than N52, high-impact collisions can still chip the plating or the ceramic core. We recommend handling them over a padded or non-magnetic surface to prevent runaway magnets and impact damage.

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 tissue, causing fatal internal damage. SEEK IMMEDIATE MEDICAL ATTENTION if ingestion is suspected.
Pinch Hazard: Large enough to cause minor skin pinches. Handle with a steady grip.
Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.
