Patent ID: 7682558

Claim:
A metallurgical powder composition for making compacted parts, comprising: (a) at least about 80 percent by weight of an iron or iron-based powder; (b) up to about 20 percent by weight of at least one alloying powder; (c) from about 0.05 to less than 2 percent by weight of a binding agent comprising C 14 -C 30 fatty alcohol; (d) from about 0.001 to about 0.2 percent by weight of a flow agent, and (e) an organic metal-free pulverulent lubricant selected from the group consisting of stearic amide, arachidic amide, behenic amide, stearylstearic amide, ethylene bis-stearamide, and combinations thereof, wherein the total amount of binding agent (c), flow agent (d), and organic metal-free lubricant (e) is from 0.1 to 2 percent by weight of said metallurgical powder composition, and wherein said binding agent (c) is present in a concentration of 10 to 90 percent by weight based on the total weight of said binding agent (c), said flow agent (d), and said organic metal-free lubricant (e).
