NGYC (Ningbo Ninggang Permanent Magnetic Materials Co., Ltd) established in 1987, is specialized in the exploitage and production of 1:5 and 2:17 sintered SmCo magnetic materials. NGYC has 450 employees and the capacity of manufacturing 1500 tons of SmCo magnets annually. It moves ISO 9001 and TS 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 16 to 25, maximum working temperature 250 degree. The BH max range of 1:17 magnet is from 20 to 32, 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 and sensors.
