摘要：Described are wrought forms of copper alloys for infiltrating powder metal parts, the method for preparing the copper alloys and their wrought forms, the method for their infiltration into a powder metal part, and the infiltrated metal part infiltrated with the novel alloys having a generally uniform distribution of copper throughout and exhibiting high transverse rupture strength, tensile strength and yield strength. Infiltrated metal parts prepared by infiltrating powder metal parts with reduced amounts of the novel infiltrant typically weigh less and have superior strengths compared to similarly prepared infiltrated metal parts prepared with standard methods and conventional infiltration.

主权项：1. A method for infiltrating a powder metal part, the method comprising: a) providing the powder metal part; b) providing a copper alloy having a homogeneous wrought form adapted to contact a surface of the powder metal part, c) contacting the alloy with a surface of the powder metal part; and d) heating the alloy and the powder metal part to a temperature sufficient to cause the alloy to melt and infiltrate the powder metal part, wherein the alloy comprises: (i) at least about 85 weight % copper; and ii) about 0.5 to about 3.5 weight % iron.
