What is the difference between NdFeB magnets and SmCo magnets?
The main difference between NdFeB (neodymium iron boron) magnets and SmCo (samarium cobalt) magnets is their composition and performance. NdFeB magnets are known for their very high magnetic strength and are the most powerful rare earth magnets available today. However, they are less resistant to high temperatures and corrosion, so they usually need a protective coating. SmCo magnets, on the other hand, have slightly lower magnetic strength but offer excellent resistance to heat and corrosion. This makes SmCo magnets more suitable for applications where the magnet will be exposed to high temperatures or harsh environments. In summary, NdFeB is best for maximum strength, while SmCo is better for stability in extreme conditions.
