METAL POWDER COMPOSITION

摘要

The present invention relates to a metal powder composition comprising: an iron or iron-based powder composition, and a lubricating combination comprising a substance A, a substance B, and a substance C; wherein: substance A is a polyolefin, substance B is chosen from a group consisting of saturated and unsaturated fatty acid amides, saturated and unsaturated fatty acid bisamides, saturated fatty alcohols and fatty acid glycerols, and substance C is an amide oligomer having a molecular weight between 500 g/mol and 30 000 g/mol; and wherein the amounts of respective substances A, B and C in weight percent of the iron or iron-based powder composition are: 0.05 = A + B < 0.4 wt%, C = 0.3 wt%, A + B + C = 2.0 wt%, and the relation between substances A and B is: B/A > 0.5. The invention also relates to a method of producing a metal powder composition and a method for producing a green component.
