The Primary Color Of The Magnets (NdFeB And Ferrite)

The primary color of the magnet (NdFeB and ferrite)

The primary color of the magnet, many people say, isn't it the color you see. In fact, it is not. Take the strong magnet NdFeB as an example, its own characteristics are easy to corrode and oxidize. Therefore, it is necessary to do a layer of electroplating surface treatment on its surface in order to better protect the magnetism of the magnet.

If NdFeB is not electroplated, its primary color is black gray, not as black as ferrite, and there will be a little residue on the hand. There are very few photos of NdFeB before electroplating on the Internet. Usually we see The neodymium iron boron that arrives is already plated, and the common ones are galvanized and nickel plated. The natural color of NdFeB is shown in the figure.

The primary color of ferrite is black, and the finished product is the same as the primary color. Since ferrite itself has the characteristics of corrosion resistance, it does not need to be electroplated, as shown in the figure.
