???? Mechanical Properties

Magnetic Properties

• Magnetization Direction: Magnetized through the thickness (2 mm).

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

• Magnetic Field Lines: Concentrated at the center and focused near the edges.

• 40 × 13 mm surface area provides a high precision advantage and alignment accuracy in narrow space applications due to its thin form factor.

• Approximate Pull Force: 2.5 – 3 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 compression.
⚠️ At temperatures above 80 °C, magnetic performance may decrease.
⚠️ Magnets can collide rapidly with each other or metal surfaces — protective gloves are recommended.
⚠️ Keep out of reach of children.
