DESCRIPTION: Materials Introduction: High Magnetic Energy Product (BHmax): Provides a strong magnetic field, enhancing the efficiency and power density of the motor (typically BHmax>40 MGOe). Good Temperature Stability and High Coercivity (Hcj): During the operation of motor, reaching high temperatures could reach of 150ºC~200ºC or even higher. Zhaobao's magnets' high coercivity (Hcj>20 kOe) offers strong resistance to demagnetization at high temperatures. Demagnetization Resistance: During rapid start-stop and reverse operations of the motor, the magnet experiences strong demagnetizing fields. Zhaobao's magnets have superior demagnetization resistance to maintain stable magnetic performance. Excellent Corrosion Resistance: Common surface treatments include Epoxy, Zinc, and Aluminum plating. Customized Shapes: Arc, Segment, Sector,Tile, Lune Grade: N30H~N54H, N30SH~N54SH, N25UH~N54UH, N28EH~N48EH Surface Treatment: Nickel(NICUNI), Zinc(ZN), Phosphorus(P), Epoxy(NICU+EP, NICUNI+EP,P+EP), Aluminum Matrix Composites Characteristics: Good coercivity, Good temperature stability, Corrosion protection, Rust prevention and High temperature resistance Selling point: High power density, reliable stability extend the motor's lifespan and enhance the overall performance of the motor Quality System: IATF 16949:2016, ISO 45001:2018, ISO 14001:2015, ISO 9001:2015, SA 8000:2014, RoHS, REACH Manufacturer: Ningbo Zhaobao Magnet Co., Ltd.
