AlNiCo magnetic powder is made of AlNiCo magnet and through cracked it into re quired particle size. The character is temperature coefficient of Br is small. The powder mainly used in raw material of bonded magnet, plastic magnet;all kinds of fault detection; magnetic printing and other highly temperature sensitivity fields.
