Mechanical Properties

 Magnetic Properties

• Magnetization direction: Magnetized through the thickness (5 mm).

• Poles: Located on the front and back square faces.

• Magnetic field lines: Concentrated at the center, focused near edges.

• 30 × 30 mm surface area provides a wide contact area and increased thickness for greater holding force.

• Approximate pull force: 6 – 7 kgf (tested on a steel surface).

⚙️ Applications

• Magnetic holding and fastening systems

• Industrial sensor and motor applications

• Mechanical prototyping and engineering projects

• Model making, CNC, and R&D projects

• Strong magnetic coupling or alignment systems

⚠️ Warnings and Usage Notes

⚠️ Neodymium magnets are very strong and brittle; they may crack under impact, shock, or pressure.
⚠️ At temperatures above 80 °C, magnetic performance may decrease.
⚠️ Magnets may attract each other or metal surfaces rapidly — protective gloves are recommended.
⚠️ Keep out of reach of children.
