FERROMAGNETIC NANO METAL POWDER |
| 摘要 |
The present invention related to ferromagnetic nano-metal powders and more particularly, to ferromagnetic nano-metal powders for increasing packing density by decreasing the porosity between micro-sized soft magnetic metal powders. According to an embodiment of the present invention, the ferromagnetic nano-metal powder allows high packing density and high magnetic property at a high frequency to fill the pores inevitably generated during the manufacturing process of an inductor using the soft magnetic metal powders. |
