摘要：
A lubricant for metallurgical powder compositions contains an oligomer of amide type, which has a weight-average molecular weight M.sub.w of 30,000 at the most. A metal-powder composition containing the lubricant, as well as a method for making sintered products by using the lubricant, are also disclosed. Further, the use of the lubricant in warm compaction is described.
