- *** Properties measure at 25°C, unless otherwise specified.
- ** The Maximum Operating Temperature for a magnet made from this powder is dependent upon the specific application, this type of magnet, and magnet geometry.
- * Maximum Process Temperature is defined here as <2% reduction in flux (i.e. structural loss) after heating powder 1 hour in air.
- ! All powders are measured under standard mesh size of -40M.
- Most compression bonded magnets exhibit a typical MQP volumetric loading of 77.5%, a typical HD powder has 80% by volume loading.
