Profile: Baotou INST Magnetic New Materials Co., Ltd. is a manufacturer of NdFeB magnets, SmCo magnet, and rare earth polishing powder. We are ISO 9001:2000 certified. Sintered samarium cobalt magnets are inherently very brittle. Conventional machining techniques cannot be processed. If machining is required, high concentration diamond grinding wheels must be used, and water or oil coolant is necessary. SmCo permanent magnet principle finds applications in servo-motors, pump couplings, and sensors.
