Comparison between Neodymium Magnets and SmCo Magnets

Neodymium magnets can replace SmCo magnets in most cases, especially where the operating temperature is less than 80 degree Centigrade, though the temperature stability of neodymium magnets is not as good as SmCo magnets. The magnetic performance of the regular neodymium magnets will go down rapidly around 80 degrees Celsius but the specially made ones can work up to 220 degree Celsius. Compared to SmCo magnets, the corrosion and oxidation resistance of neodymium magnets are relatively low.
