What causes magnets to rust?
Common magnets are NdFeB magnet magnets, which are particularly prone to rust and are generally protected by plating. Samarium cobalt magnets will also rust, samarium cobalt magnets are composed of iron (Fe) elements, as long as the products containing iron elements will rust. According to the amount of content to judge the speed of rust, rust will also be related to the working environment.
What is the difference between the rusting of samarium cobalt magnets and NdFeB magnets. Compared with NdFeB, samarium cobalt has low iron content and less serious rust. When samarium cobalt magnets are put into seawater, the surface of the product will rust, but it will not affect the performance and use.
Why should samarium cobalt magnets be electroplatedWe know that cobalt magnets can be plated with nickel, zinc, nickel, copper, nickel, epoxy and other electroplating treatments. So why plating? Doesn't electroplating increase the cost again? In fact, samarium cobalt magnet plating has three main benefits.
First, the appearance of beautiful --- electroplated samarium cobalt magnet looks not so rough, it appears much smoother.
Second, prevent rust--- Although samarium cobalt magnets have strong anti-rust ability, electroplating is better.
Third, prevent crushing--- samarium cobalt magnets are still relatively easy to break, electroplating can effectively solve the problem of fragility.
