一、前言1.金属磁粉的用途金属磁粉是指单质铁和铁基合金等强磁性粉末。在涂布型磁记录介质中,金属磁粉具有良好的特性,如γ-Fe_2O_3磁粉的矫顽力在15.92~35.82 kA/M 之间,而金属磁粉的矫顽力高达55.72~167.16 kA/m。用金属磁粉制成的磁带称金属磁带(或金属带),
I. Preface 1. The use of metal magnetic powder Metal magnetic powder is strong magnetic powder such as simple iron and iron-based alloy. In coated magnetic recording media, metal magnetic powder has good properties, such as γ-Fe 2 O 3 magnetic coercive force between 15.92 ~ 35.82 kA / M, while the metal magnetic coercive force as high as 55.72 ~ 167.16 kA / m. Magnetic tape made of metal powder called metal tape (or metal tape),
