Abstract
High strength ductile sintered iron alloy composition containing silicon and phosphorus with a total alloy content below 4% having a yield point above 400 N/mm.sup.2 and an impact strength of more than 40 J/cm.sup.2. The alloys contain between about 0.5 and 3% by weight silicon, and between about 0.2 and 0.7% phosphorus, with the balance being iron. These alloy compositions are made by sintering iron, iron-silicon and iron-phosphorus powders at temperatures between about 1050.degree. and 1200.degree. C.
