Introduction To Corrosion Resistance Of Different Magnetic Materials
Permanent magnet materials contain iron elements, iron shows the most significant ferromagnetic properties of all elements, which is why it exists in the most powerful magnets. However, iron is highly reactive to water, making magnets with a high iron content very susceptible to corrosion. Other ferromagnetic elements used in different types of permanent magnets include nickel, cobalt, gadolinium, and dysprosium, all of which have an effect on magnetic strength and corrosion resistance. There are many factors to consider when exploring custom magnetic components, and corrosion resistance is one of the key factors you just considered, so take a look at our breakdown of the corrosion resistance of each magnetic material. 1. NdFeb magnet Currently, the strongest commercial permanent magnet on the market is Ndfeb magnets , but due to their high iron content (64-68%), they are also highly corrosive in wet environments. Modern manufacturing techniques have found that small amounts ...
