PROBLEM TO BE SOLVED: To provide an aluminum-containing copper-based alloy powder to be sintered which can provide a sintered compact having sufficient hardness and radial crushing strength, when having been compacted in an atmosphere containing nitrogen by a powder metallurgy process.;SOLUTION: The alloy powder to be sintered is prepared by adding 0.02 to 20.5 mass% of a fluoride which includes either or both of 20 mass% or less of calcium fluoride and 0.5 mass% or less of aluminum fluoride, and 0.05 to 0.5 mass% of phosphorus which is contained in a phosphorus alloy, with respect to an aluminum-containing copper-based alloy powder to be sintered. In addition, an inorganic solid lubricant may be added to the powder, as needed.;COPYRIGHT: (C)2009,JPO&INPIT
