Magnetic Materials: FAQ

How can I ensure the magnet dimensions are accurate?

Always check the product description for dimensions in millimeters (mm) rather than relying on photos. Manufacturers provide tolerance levels; look for +/- 0.05mm for high-precision needs.

How do I verify the grade of Neodymium magnets?

Look for the 'N' rating, such as N35 or N52. Higher numbers indicate stronger magnetic fields, though N52 is typically the maximum for reliable commercial-grade magnets.

What coating is best for preventing rust on magnets?

Choose magnets with Ni-Cu-Ni triple-layer plating for the best corrosion resistance. For outdoor or humid use, epoxy coatings provide an even higher level of protection.

Are there special shipping rules for strong magnets?

Yes, powerful magnets require shielded packaging for air freight safety. Reputable AliExpress sellers use specialized metal-lined boxes to comply with international shipping regulations.

Recommendations for buyers

✓
Pull Strength Verification
Always verify the vertical pull strength rating in the specifications to ensure the magnet can safely hold the weight required for your project.
✓
Temperature Resistance
Standard Neodymium magnets lose magnetism above 80°C. If your application involves heat, look for 'SH' or 'UH' grade materials rated for higher temperatures.
✓
Magnetization Direction
Confirm if the magnet is axially magnetized (through the thickness) or diametrically magnetized (across the diameter) to ensure it fits your assembly design.
✓
Material Brittleness
Rare-earth magnets are naturally brittle. Ensure the seller provides adequate protective plating and check reviews for mention of durability during transit.
