It can also rust. Because samarium cobalt magnets contain iron, they can rust. However, compared to neodymium iron boron magnets, it has a lower iron content, so the rusting phenomenon is not very serious. If samarium cobalt magnets are used in seawater, some rust spots may appear on the surface of the product, but it does not affect its performance and use.

Why do samarium cobalt magnets need electroplating?

We know that samarium cobalt magnets can be used for electroplating treatment, such as nickel plating, zinc plating, nickel copper nickel, epoxy, etc. So why electroplating? Isn't electroplating adding some cost? In fact, there are three main benefits to electroplating samarium cobalt magnets.

1、 Beautiful appearance. The electroplated samarium cobalt magnet looks less powdery, so it looks much better.

2、 Rust prevention. Although samarium cobalt magnets have strong rust resistance, electroplating is better.

3、 Anti crushing. Samarium cobalt magnets are relatively fragile, and electroplating can effectively solve the problem of fragility.
