Rare Earth Magnets are composed partly by one or more rare earths as defined by the USGS. The two most widely known rare earth magnets are: Samarium Cobalt (SmCo) - Energy products go up to 32 MGOe, can typically be used in high temperature (350°C) environments, and typically have a small thermal coefficient of Br (approximately 0.03%/degree) Neodymium Iron Boron (NdFeB) - Energy products go up to 52 MGOe, can generate very high fields; however, NdFeB typically needs to be used in lower temperature applications than Samarium Cobalt can withstand. Higher temperature coefficient of Br (approximately 1.1%).
MCE offers standard parts to be used for your next project, see below for our standard part availability.
