COMPOSITE BRAZING FILLER METAL, COMPOSITE MATERIAL FOR BRAZING, AND BRAZED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a new composite brazing filler metal which has excellent heat resistance and corrosion resistance, and has satisfactory fluidity and brazing operability, to provide a composite material for brazing, and to provide a brazed product.;SOLUTION: The composite brazing filler metal consists of a stacked body obtained by stacking a nickel layer consisting of nickel or a nickel alloy, and a tin layer consisting of tin or a tin alloy. Thus, the brazing filler metal can exhibit heat resistance and corrosion resistance more excellent than those of the conventional one, therefore can maintain excellent joining strength, and, further has satisfactory fluidity compared with a nickel simple substance, and is made easy to be treated compared with the powdery one, so that its brazing operability remarkably improves.;COPYRIGHT: (C)2003,JPO
