8mm x 8mm x 8mm (5/16" Cube) Neodymium Magnet – N52 Grade 

Key Features:

• Dimensions: 8mm x 8mm x 8mm (Equilateral Cube)
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 8.4 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized (Poles on two opposite flat faces)
• Surface Gauss: Approx. 6,100 Gauss

Material Description:

Our 8mm N52 cubes are engineered for high-performance applications that demand a concentrated magnetic field in a symmetrical, non-rolling format. The cubic geometry allows for seamless integration into CNC-machined recesses or 3D-printed housings, providing vastly more magnetic flux than a standard disc. These are widely used in robotics for magnetic end-effectors, heavy-duty industrial proximity sensors, and advanced modeling projects where a powerful "lock" is essential.

Handling Advice: DANGER: These magnets are exceptionally powerful for their size. With over 8 lbs of pull force, they can snap together from several inches away with enough speed to shatter or cause painful skin pinches and blood blisters. Always handle with a firm grip and separate by sliding horizontally. Use non-magnetic tools to maintain the integrity of the nickel coating.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause serious skin pinches. Handle with caution.
• 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.
• Brittleness: Neodymium is a ceramic; high-impact collisions will cause shattering. Never let them slam together.

Applications:

• Heavy-duty magnetic latches for cabinetry, secret doors, and hidden panels
• High-performance proximity sensors and robust magnetic triggers for automation
• Industrial-strength modular mounting systems and workshop organization
• Custom high-torque magnetic couplings for robotics and RC prototypes
• Structural joinery for high-end furniture and art installations
