Abstract

PURPOSE:To provide excellent wear resistance as well as high strength and high toughness to the titled alloy by specifying the contents of C, Cr, Mo, Si, Mn, Co, W, Ta, Ti, Al, Hf and Ni in the Fe based cast alloy. CONSTITUTION:The compsn. of the Fe based cast alloy for a rocker arm is constituted of, by weight, 2.5-4% C, 20-40% Cr, 0.01-1% Mo, 1-4% Si, 0.1-1% Mn, 0.1-1% Co, 0.05-1% W, 0.01-1% Ta, 0.01-1% Ti, 0.01-0.1% Al, 0.001-0.1% Hf, 1-5% Ni and the balance Fe with inevitable impurities. Since said cast alloy has high strength and high toughness as well as shows low offensiveness against the mating members and has excellent wear resistance, the miniaturization and thinning of a rocker arm can be attained.
