, molybdenum disulfide (Mo5s) 1-1514. These generally exhibit lubricity in their respective temperature ranges, and act as coefficient improvers when their respective temperature ranges are exceeded. In this case, lead and zinc, which are common lubricating ingredients, are not added based on the knowledge that a high coefficient of friction cannot be maintained due to the thermal fade phenomenon. , the number of scratches from 70 scratches is about 0.4 to 0.6, which means that they belong to the category of high Q button scratches, so they are actively excluded.

Furthermore, in the dry sintered friction material of the present invention, manganese is added to the material in an amount of t15 or less. This is because the amount of manganese added has the effect of reducing the oxide film of the sintered medium-value metal and improving sinterability. Also, some of the manganese is MnO! This is because it has an effective effect of stabilizing the friction surface metal.
