Contact more customers, there will always be a lot of questions, such as a user asked, ferrite magnet can be saved for how long? Does oxidation of ferrite affect its properties?

Today I will reply to these two questions.

 

Ferrite, also known as permanent magnet ferrite, chemically known as ferric oxide, is already an oxide of iron, and it is difficult to be oxidized again. For the magnetic ring, its characteristics are long-term, there will be no deterioration, but put for a long time, there will be residue on the surface - some powder, this is a normal phenomenon, does not hinder its characteristics.

 

As we all know, ferrite magnet is made of a variety of magnetic materials, so put for a long time, the magnet will appear powder, which is what we say in the industry oxidation, but this does not affect its magnetic properties and impedance characteristics. The magnet will also be easy to oxidize when it encounters moisture, especially in wet weather. If the magnetic ring of the packaging is not sealed well and the moisture runs into the carton, it will also lead to oxidation of the magnetic ring.

 

Many people will ask, the magnet in production is not through water to clean the surface? How can also be afraid of water, of course, the magnetic ring is through the water to wash off the dirty surface, but after cleaning, the magnet to enter the oven to dry water, so just made of the magnet, not oxidation, and just washed out of the magnetic ring appearance, shiny!
