Iron-based sintered alloy, iron base sintered alloy member, method for production thereof, and oil pump rotor
摘要：
An iron-based sintered alloy member having a composition consisting of 0.5 to 7% by mass of Cu, 0.1 to 0.98% by mass of C, 0.02 to 0.3% by mass of oxygen and, optionally, 0.0025 to 1.05% by mass of Mn and/or 0.001 to 0.7% by mass of Zn, and the balance of Fe and inevitable impurities is manufactured by formulating an Fe powder, a graphite powder and a Cu alloy powder, as raw powders, mixing the powders to form a powder mixture, forming the powder mixture into a green compact and sintering the green compact. The Cu alloy powder has a composition consisting of 1 to 10% by mass of Fe, 0.2 to 1% by mass of oxygen and, optionally, 0.2 to 10% by mass of Zn and/or 0.5 to 15% by mass of Mn, and the balance of Cu and inevitable impurities.
摘要（中）：

一种铁基烧结合金构件，其组成为：Cu：0.5〜7质量％，C：0.1〜0.98质量％，氧0.02〜0.3质量％，Mn：0.0025〜1.05质量％ 和/或0.001〜0.7质量％的Zn，其余的Fe和不可避免的杂质通过配制Fe粉末，石墨粉末和Cu合金粉末作为原料粉末制成，将粉末混合形成粉末混合物， 将粉末混合物形成生坯并烧结生坯。 Cu合金粉末的组成为：Fe：1〜10质量％，0.2〜1质量％的氧，0.2〜10质量％的Zn和/或0.5〜15质量％的Mn， 余量为Cu和不可避免的杂质。
