摘要：
A valve guide member for internal combustion engines is formed of an Fe-based sintered alloy having excellent wear and abrasion resistance, consisting essentially, by weight %, of 1 to 4% C, 1.5 to 6% Cu, 0.1 to 0.8% P, and if required 0.05 to 1% Mo, and the balance of Fe and inevitable impurities, the Fe-based sintered alloy having a structure having a matrix formed mainly of pearlite, in which are dispersed hard Fe--C--P compounds and free graphite, or alternatively hard Fe--C--P compounds, carbides, and free graphite when the alloy contains Mo, the free graphite including 0.5 to 10 area % coarse free graphite having a particle diameter of 70 to 500 .mu.m.
