A wear-resistant iron-based sintered contact material is provided which is
sintered by powder sintering so as to have high density, high seizure
resistance and wear resistance. A wear-resistant iron-based sintered
composite contact component composed of the wear-resistant iron-based
sintered contact material sinter-bonded to a backing metal and its
producing method are also provided. To this end, at least
Cr.sub.7C.sub.3-type carbide and/or M.sub.6C-type carbide which have an
average particle diameter of 5 .mu.m or more are precipitately dispersed
in an amount of 20 to 50% by volume within an iron-based martensite
parent phase which has a hardness of HRC 50 or more even when tempered at
up to 600.degree. C.
