Abstract
PURPOSE: To enhance the corrosion, heat and wear resistances of the resulting titled alloy in lead-free and lead-contg. combustion atmospheres by providing a specified composition consisting of C, Cu, Ni, Cr, B and the balance Fe.
CONSTITUTION: This sintered Fe alloy for a valve seat has a composition consisting of. by wt., 0.4W2% C, 0.5W5% Cu, 0.5W5% Ni, 0.5W5% Cr, 0.005W0.5% B and the balance Fe with inevitable impurities or further contg. 0.2W5% one or more among CaF2, BaF2 and BN dispersed finely on the grain boundaries of the alloy matrix. This sintered alloy has superior machinability besides said resistances, so it is easily cut into a valve seat.
