Do magnets rust ?

Hello, welcome to courage magnet website. We are a China magnet supplier. We mainly supply rare-earth Nd-Fe-B magnets, permanent ferrite magnets, arc magnets and multi pole magnetic rings for motors. If you need to purchase, welcome to email us.

What I'm going to introduce to you today is the topic of magnet rust. Do magnets rust ? Here is a detailed introduction.

At present, some magnets commonly used in the market are neodymium magnets, ceramic magnets, samarium cobalt magnets (of course, there are other materials, which will not be highlighted here). Will they all rust? Which magnet rust most easily?

Neodymium magnet will rust, because it contains iron composition (NdFeb), accounting for about 63.95-68.65%, so the magnet manufacturer will coat the magnet before leaving the factory.

It is difficult for ferrite to rust. The chemical name of ferrite magnet is Fe3O4. The main component is Fe3O4, which is already the oxide of iron, So it is very difficult to be oxidized again.

SmCo magnets also rust, because they also contain iron, so they rust. However, compared with neodymium iron boron magnet, its iron content is relatively low, accounting for about 14-17%, so the rust phenomenon will not be very serious.

The above is about the rust of magnet. Thank you for reading.
