What advantages and disadvantages of samarium-cobalt magnets?
■ advantages
It's have a high magnetic properties, second only to neodymium magnet. It is suitable also relatively high temperature use excellent temperature characteristics. In addition, because the rust resistant, there is no need for surface treatment usually. Production of a shape depending on the application by the machining is also available.
■ Disadvantages
currently yield less domestic situation of raw material producing country is unstable, it will be expensive compared to other magnets. There is a disadvantage that the mechanical strength is low, easily chipped or cracked.
