Features
1. High precision;
2. Excellent magnetic properties;
3. Stable working temperature;
4. Good corrosion-resistance and nice surface.
Applications
1. The compression molding magnets, as for simple mould and high magnetic properties, are widely used in stepping motor, CD-ROM spindle motor, general motor, vibrating motor, pick-up, HDD spindle motor, and FDD spindle motor.
2. The injection molding magnets, as for complex mould, magnetic properties around 6 to 7 MGOe, and highly consistency, are widely used in electric expansion valve, air-condition motor etc.
