Notes
1.The properties given above are typical data at room temperature(25±3ºC).
2.Because bonded magnets are so versatile,this is just a dominant grade table.The magnetic properties can be adjusted to achieve customer's special request.
3.The Max. Working temperature is subject to specific application,type of magnet,and magnet geometry.
