Document Type and Number:
WIPO Patent Application WO/2015/156066
Kind Code:
A1
Abstract:
Provided is a nickel brazing filler metal with which various types of stainless-steel members can be brazed at a comparatively low temperatures, and which is provided with moderate material strength and exceptional corrosion resistance, the nickel brazing filler metal being used for brazing heat exchangers and the like. The present invention has a melting temperature of 1000°C or less, exhibits corrosion resistance with respect to acid, and contains 15.0-30.0 mass% of Cr, 6.0-18.0 mass% of Cu, 1.0-5.0 mass% of Mo, 5.0-7.0 mass% of P, 3.0-5.0 mass% of Si, and 0.1-1.5 mass% of Sn, the balance being Ni and unavoidable impurities, and the total of Si and P being 9.5-11.0 mass%. In addition, the present invention may contain one or more elements selected from the group consisting of Co, Fe, Mn, C, B, Al, and Ti; when these elements are included, the Co content is 5.0 mass% or less, the Fe content is 5.0 mass% or less, the Mn content is 3.0 mass% or less, and the total content of C, B, Al, and Ti is 0.5 mass% or less, the total contained amount of said elements being 10.0 mass% or less.
