Representative quality
| Item | Unit |
Analysis value (before coating) |
Analysis value (after coating) |
|---|---|---|---|
| Accumulative 50% diam. | µm | 12.31 | 12.35 |
| Tap density | Mg⁄m³ | 4.16 | 4.38 |
| Surface area | m²⁄g | 0.33 | 0.19 |
|
Oxygen |
mass% | 0.15 | 0.38 |
| Insulation resistance (100V) | MΩ | ～200 | 10000～ |
It is shown that the insulation effect is obtained from the improvement of the resistance value by coating the iron alloy powder with low insulation resistance with the insulation material.
＜Heat resistance test(200℃)＞
Even in the heat resistance test, the coated product showed no deterioration in magnetic permeability, indicating that the effect of the coating continues.
