Abstract: A process for the manufacture of sintered metal articles includes the steps of selecting a prealloy powder having a composition consisting essentially of 10-18% chromium, 2-6% iron, 2-6% silicon, 2-6% boron, 0.5-2% carbon, balance nickel, mixing the prealloy powder with copper powder in an amount equal to between 20% and 50% of the weight of the total of prealloy powder and copper, preferably adding a small percentage of a suitable lubricant, pressing the mixture to form a compact, and sintering the compact in the range 1050.degree.-1100.degree. C. for such a time that the copper and the nickel-rich prealloy only partly dissolve in one another.
