Abstract (en)
To provide a sintered alloy valve guide having high thermal conductivity and excellent wear resistance, which can be used in engines subjected to a large thermal load due to downsizing, direct injection and supercharging, the sintered alloy has a composition comprising by mass 10-90% of Cu, 0-10% of Cr, 0-6% of Mo, 0-8% of V, 0-8% of W, and 0.5-3% of C, the balance being substantially Fe and inevitable impurities, the total amount of Cr, Mo, V and W being 2% or more, and a structure comprising an Fe-based alloy phase, a Cu or Cu-based alloy phase, and a graphite phase.
