摘要： PURPOSE:To manufacture the title alloy having excellent wear resistance and strength at low cost by dispersing an Mo2C into a high-carbon Fe sintered alloy contg. specific amounts of Ni and Co in a specific ratio and infiltrating Pb according to necessary. CONSTITUTION:To iron powder, graphite powder, 0.3 to 1.5%, by weight, total 3 to 20% of Ni and Co powder and Mo2C powder regulated to 3 to 15% for the iron powder are mixed, to which trace amounts of zinc stearate as a lubricant is added to mix. The mixed powder material is pressurized to compact under high pressure and is thereafter sintered at high temp. in an ammonium cracked gas. Or, 1 to 20% Pb is furthermore infiltrated into the fine pores of the sintered body, by which the iron sintered alloy for a valve seat having excellent wear resistance and strength as a seat material for an exhaust valve of an internal combustion engine can be manufactured.
