The surface treatment of NdFeb magnet is not to improve its performance, and the surface coating of neodymium magnet mainly plays a protective role. No surface coating of NdFeb strong magnets, it is easy to react with oxygen in the air and quickly oxidize, so in order to prevent this from happening, we usually carry out plating treatment. Moreover, the appearance of the strong magnet after electroplating is more beautiful.

The gold-plated coating is used as an FDA-approved medical coating for use in vivo, and it is used as a base coating for Ni-Cu-Ni. Like the nickel coating, it helps protect the magnet from corrosion in the ambient air, but can also provide mild protection against moisture, water or salt water. The thickness of gold is very thin (about 0.1-1um), so its performance in salt spray tests may be poor, as most gold coatings are designed to be thin. Its maximum operating temperature is about 200°C.
1. Grade of NdFeB magnets.
If your application is only at room temperature, the N-series is the best choice, with a maximum operating temperature of 80 degrees Celsius. In general, the N35 is relatively cost-effective, and the magnetic force is also relatively strong.
But which level you choose depends on your pursuit or application of magnetism.
The higher the resistance temperature of the magnet, the more expensive the price. For example, the N35 class and the N35M class have the same magnetic force, but the maximum operating temperature of the N35M is 100 degrees Celsius, and the N35 is only Celsius.

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.
