NdFeB magnets and SmCo magnets both belong to the rare earth magnet family but have different properties and uses. NdFeB magnets provide the strongest magnetic force, making them ideal for compact, high-power devices.
What is the difference between NdFeB magnets and SmCo magnets?
NdFeB magnets and SmCo magnets both belong to the rare earth magnet family but have different properties and uses. NdFeB magnets provide the strongest magnetic force, making them ideal for compact, high-power devices. However, they can lose performance in high heat and are more likely to rust without special coatings. SmCo magnets are less powerful than NdFeB but can withstand much higher temperatures and are naturally resistant to corrosion. As a result, SmCo magnets are often used in aerospace, automotive, and other demanding environments. If your application needs the strongest magnet possible, choose NdFeB; if you need stability in tough conditions, SmCo is the better choice.
