Product description
Bonded NdFeB magnet are compound from magquench powder with
adhesive and coated with special paint which is popular in various
motors produced in developed countries.Customers' special
requirements of different magnetic properties can be also achieved
by adjusting the ingredients and compositions of the powder
material.
Application
Bonded NdFeB magnet are most applicable in mirco-motors used in
computer and its peripheral apparatus,OA,digital product,high grade
domestic appliances and automobiles,such as spindle motor for
HDD,FDD,CD/DVD-ROM,linear motor,vibration motor,stepping
motor,servo motor,transducers etc.

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.
