A sintered alloy composition for automotive engine valve seats, and a method for producing the same, are described. An iron base sintered alloy composition comprising vanadium carbide particles, Fe-Co-Ni-Mo alloy particles, and Cr-W-Co-C alloy particles in which the composition is dispersed in a structure of sorbite is particularly suitable for use as materials of valve seats for automotive engines which requires excellent wear resistance, high-performance, high-rotation-speed, and low-fuel-consumption.
