ABOUT NICKEL BRAZING ALLOYS. The nickel brazing alloys are generally used when specifications call for corrosion resistance and high-temperature service properties but can also be used in subzero applications as low as the temperature of liquid oxygen, helium, or nitrogen. Nickel brazing alloys have low vapor pressure,

Atmosphere furnace brazing. For high-temperature applications (up to 370 °C), e.g. on jet engines. Zinc free; used instead of BAg-13 where zinc fumes in the furnace are not allowed. Similar to BAg-13. Tends to liquate. Can be used for wide gap joints. Can be used with flux, but mostly used for fluxless furnace brazing of stainless steel in dry hydrogen.

METAL JOINING PRODUCTS BRAZING ALLOYS, BRAZING FLUX

Silver-Copper-Phosphorus Alloys are widely used alloys for copper-to- copper brazing because of the self-fluxing properties from the phosphorus content. Not for use with ferrous or nickel based materials. High purity alloys are used for the brazing of carbides, steel, cast irons, and other ferrous alloys.

Jun 12, 2018 · 3.1 surface oxides should be removed carefully before brazing high-temperature alloy. 3.2 the brazing temperature of high temperature alloy should be consistent with its heat treatment system as far as possible. If the material heat treatment system has no special requirements, the brazing temperature can be determined according to the used solder. 3.3 the vacuum degree shall be controlled over 10-2pa to prevent the formation of new oxides on the surface of high-temperature alloys during

High-temperature brazing: filler metals and processing

Brazing was carried out at a relatively high temperature, about 1175 °C, because BNi-5b (MBF-51) contains low boron and high chromium concentrations. Interaction of 316 L austenitic steel with BNi-5b (MBF-51) yields brazements in which a (Ni,Fe,Cr,Si) solid solution phase constitutes a large part of the joint area microstructure.

Nickel Brazing Below 1025 C of Untreated Inconel 718

Cr-Fe high temperature alloys — e.g. Inconel 718 and X-750* — produces in these nickel alloys surface oxides which are very difficult to reduce and wet in a vacuum or in a dry hydrogen atmosphere. Therefore brazing of these alloys normally requires a vacuum better than 10-5mm Hg and brazing temperatures higher than 1075 C(1970 F).
