Abstract: An alloy powder composition for a connecting rod includes 0.5 to 0.8% by weight of carbon (C), 0.8 to 1.2% by weight of copper (Cu), 1.6 to 2.0% by weight of chrome (Cr), 0.4% by weight or less but greater than zero (0) of manganese (Mn), 0.2% by weight or less but greater than 0 of sulfur (S), a remainder of iron (Fe), and other unavoidable impurities, based on 100% by weight of the alloy powder composition.
