INDIANAPOLIS, Ind., Feb 27, 2007 – As the PM industry continues to investigate new higher performance materials and processes, a re-examination of the copper infiltration process for high strength, as-sintered products is introduced using a new infiltrant form. A wrought copper alloy wire product has been shown to offer an excellent infiltration response for the FX-1008 copper infiltrated steel grade. A complete set of mechanical properties for several levels of infiltrant and skeletal densities are provided. Very high infiltrated densities (greater than 7.7 g/cm3) were achieved for this 15% maximum copper grade. Comparisons are drawn with conventional compacted powder infiltrants as well as the properties reported in MPIF Standard 35 for this alloy. The advantages of using this wrought wire form for the copper infiltration process are also presented.
