世界磁性材料市场容量巨大现在世界汽车产量在5500万辆左右,按每辆汽车使用电机数30只计算,预测需要电机16亿只。随着汽车生产量和使用扬声器数量的增加,汽车用的扬声器产量将达2.3亿只。预测与上述器件配套的铁氧体永磁25万吨。由于电动车的发展以及为了保护环境而采用非汽油驱动汽车,需要应用新材料提高电机的功能,并减小尺寸,这促进了钕铁硼磁体加速发展。估计到2007年世界永磁体的产值将超过100亿美元。计算机的发展带动了相关配套元件的发展,预计2010
World Magnetic Material Market Has a Great Capacity Now the world’s automobile production is about 55 million vehicles, and the number of motors used per vehicle is 30, which is predicted to require 1.6 billion motors. With the increase in car production and use of loudspeakers, the output of car speakers will reach 230 million. It is estimated that 250,000 tons of ferrite permanent magnet are matched with the above devices. Due to the development of electric vehicles and the adoption of non-gasoline-driven vehicles for the sake of the environment, the application of new materials to improve motor functions and reduce the size has accelerated the accelerated development of neodymium-iron-boron magnets. It is estimated that by 2007 the world’s permanent magnet output value will exceed 100 billion US dollars. Computer development led to the development of related components, is expected in 2010
