摘要： Sintered iron alloy composition and method of manufacturing the same, the sintered alloy composition comprising: about 1.5 to about 2.5% carbon by weight; about 0.5 to about 0.9% manganese by weight; about 0.1 to about 0.2% sulfur by weight; about 1.9 to about 2.5% chromium by weight; about 0.15 to about 0.3% molybdenum by weight; about 2 to about 6% copper by weight; not more than about 0.3% by weight of a metal element material comprising at least one member selected from the group consisting of tungsten and vanadium; an effective content of a first solid lubricant material comprising at least one member selected from the group consisting of magnesium metasilicate minerals and magnesium orthosilicate minerals; and balance iron. This alloy composition is preferably used for making machine parts, such as slide members of valve operating systems for internal combustion engines.
