Detailed Product Description

    The flux output of the Samarium Cobalt (SmCo) magnets is more stable with changes in temperature than NdFeB magnets due to having better temperature coefficients (e.g. -0.030%/°C for change in Br versus -0.100%/°C for NdFeB and -0.20%/°C for change in Hci versus -0.60%/°C for NdFeB). This can be particularly useful in critical applications such as sensors (although Alnico can be a better choice for temperature stability). It also means that Samarium Cobalt can resist demagnetisation better than Neodymium in higher temperature applications such as motors.
