NGYC (Ningbo Ninggang Permanent Magnetic Material Co., Ltd) established in 1987, is specialized in the exploitage and production of 1:5 and 2:17 sintered SmCo magnetic materials. NGYC has more than 400 employees and the capacity of manufacturing 1500 tons of SmCo magnets annually. It moves ISO 9001 and IATF 16949, and more than 80% of products have been exported to US, Europe and other countries worldwidely.


1:5 and 2:17 magnets are with different properties and grades after series technology processing from melting, milling, and pressing to sintering in order. The BH max range of 1:5 magnet is from 14 to 25, maximum working temperature 250 degree. The BH max range of 1:17 magnet is from 22 to 33, maximum working temperature 350 degree. 2:17 magnet bears an extremely low temperature coefficient and preferably anti-causticity. In high-temperature conditions, the magnetic properties is better than NdFeB magnets, As a result, it’s widely used in fields such as aeronautics and space, national defense, motors, sensors and microwaves etc.

In recent years, NGYC has desined and finally succeed to make a hinger grade of YXG-33H and is continue to research the better grades.
