Abstract

There is provided an iron-based mixture powder for sintering, as well as an iron-based sintered alloy using same, that are capable of reducing the cutting resistance of the iron-based sintered alloy and of mitigating the shortening of cutting tool life even when a metal fluoride powder is used. The iron-based mixture powder for sintering comprises an iron-based powder, a graphite powder, a hard powder that is harder than the iron-based powder, and a metal fluoride powder. With respect to particle asperity as expressed by the following equation, particle asperity = (perimeter of a section of a particle)2 / (sectional area of the section x 4Pi), the particle asperity of the metal fluoride powder is within the range of 2 to 5.
