MIXED POWDER FOR SINTERED ALUMINUM-CONTAINING COPPER ALLOY, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide mixed powder for a sintered Al-containing Cu alloy capable of obtaining a Cu-Al sintered alloy having satisfactory moldability, having high safety upon handling, and dense and having excellent characteristics even at a low sintering temperature of ≤900°C, and to provide a method for producing the same.;SOLUTION: Al-Cu partially dispersed alloyed powder obtained by subjecting mixed powder composed of Al powder of 40 to 60 mass%, and the balance Cu powder is subjected to heating treatment at 540 to 560°C for 10 to 60 min in a reducing or inert atmosphere and pulverizing the same or mixed powder for a sintered Al-containing Cu alloy using Cu-coated Al powder obtained by immersing Al powder into a Cu salt aqueous solution and precipitating 40 to 60 mass% Cu as an Al source is admixed with the three components of 0.05 to 1% P, 0.5 to 4% Si and 0.1 to 1% Sn.;COPYRIGHT: (C)2009,JPO&INPIT
