Frequently Asked Questions

High coercivity magnets are specially engineered rare earth magnets that resist demagnetization, even under extreme heat or magnetic stress. They maintain stable performance at elevated temperatures where standard neodymium magnets would lose strength.

They are commonly used in electric motors, actuators, hard drives, speakers and industrial applications that require long-term stability in demanding environments.

Depending on the grade, high coercivity neodymium magnets can operate up to 220°C (428°F), while samarium cobalt magnets offer even higher temperature stability. NdFeB provides stronger magnetic performance at lower cost but is more sensitive to heat and corrosion, while SmCo offers superior high-temperature and corrosion resistance at a higher cost with lower magnetic strength.The exact rating depends on the application and magnet grade.

Standard neodymium magnets begin to lose strength at elevated temperatures, whereas high coercivity magnets are designed with enhanced material properties to retain their magnetic field and resist thermal demagnetization.
