The application of ferrite is quite wide, and the amount is also very large. Why use ferrite magnets? This is because it does not rust, oxidize, corrode, and is environmentally friendly. Then why does it not rust, the Shanghai magnet manufacturer will tell you below.
The chemical name of ferrite magnet is ferroferric oxide, and its main component is Fe3O4. It is already an iron oxide, and it is more difficult to be oxidized again. Other magnets are made of magnetized metallic iron or other elements because the main component is iron, so they are easily oxidized and rusted, and the oxidized part will lose magnetism.
The above is the reason why the ferrite magnet does not rust.
