Abstract
An improved metallurgical powder composition comprising an iron-based powder and an alloying powder is provided. The composition contains a polyalkylene oxide having a number average molecular weight of at least about 7,000 as a binder. The binder of this invention permits the bonded powder composition to achieve compressibility equivalent to that of unbonded compositions and maintains resistance to dusting and segregation of the alloying powder.
