???? Mechanical Properties

Feature	Value	Description
Hardness	600 HV	Brittle structure – low impact resistance
Compressive Strength	1000 MPa	High-density structure
Tensile Strength	75 MPa	Measured in the magnetic surface direction
Thermal Expansion Coefficient	6.5 × 10⁻⁶ / °C	Limited thermal stability

???? Magnetic Properties and Structure

Magnetization direction: Magnetized through the 20 mm thickness (height).

Poles: Located on the top and bottom 40 × 40 mm surfaces.

Magnetic Field Lines: Intensified in the center of the surface and focused toward the edges.

Surface Area: The 40 × 40 mm square surface provides a very strong grip and precise alignment thanks to its wide contact area.

Approximate pull force: 12 – 16 kgf (when tested on a steel surface – noticeably stronger than smaller dimensions).

⚙️ Applications

High-strength magnetic holding systems
Large surface alignment and clamping applications
CNC, jig, fixture, and heavy engineering setups
Powerful industrial sensor, motor, and magnetic locking systems
R&D and prototyping projects requiring high magnetic force

⚠️ Warnings and Usage Notes

⚠️ Neodymium magnets are extremely powerful – they can snap to metal surfaces rapidly and may crack.
⚠️ Impact resistance is low, controlled placement is recommended.
⚠️ Magnetic performance decreases above 80 °C.
⚠️ If magnets collide with force, they may crack – wearing protective gloves is recommended.
⚠️ Keep strictly out of reach of children.
