1.Grade of NdFeB magnet.

Neodymium magnets are graded according to their material. In general, the higher the score (the number after N),the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH.

FAQ

 

Q1. Why is the price of sample higher than that of batch?

A: For samples we don't have any profit. We only charge the cost of materials and labor. As a manufacturer, the more quantity produced, the lower the unit cost.

 

Q2. Why I should pay the Magnetic inspection fee? What is Magnetic inspection fee?

A: The freight is only paid by us to the transportation company for you, and the magnetic inspection fee is also a necessary cost generated in the process of transportation. 

Freight companies require magnetic inspection reports when transporting magnets.Magnetic inspection report is a report provided by a professional magnetic inspection agency after testing that the magnet meets the transportation standards.

 

Q3.Why do I get magnets that break so easily?

A: Magnets are designed to be brittle and fragile. Remove the metal from the working area before using the magnet. Keep the distance between the magnets when using them at the same time. Even small magnets attracted to each other can break with such force.

 

Q4. Do you support exchange and return service?If I buy a magnet and I can't use it.

A: We do not support return or exchange service. As you know, the magnet is a custom product, which is completely customized according to your requirements. This product cannot be resold to others.

 

Q5. What will you do if there is a quality problem?

A: If you have any problem after receiving the magnet, please contact us immediately and shoot a video to us. We make records and take pictures of all the details when we ship. If it's our fault, we'll take the blame. If it happened in transit, we are not responsible for it.
