Zr-Ti-Ni (Cu) based low melting point brazing filler metal alloy composition for Chitanrou with

摘要

Topic Melted temperature was low, could hold down the content of the copper element, titanium low offer the filler material metal which does not decrease the durability of the assembly body which is attached.SolutionsAs for this invention, Zr Ti Ni for the titanium low attaching (Cu) system in regard to the fusion point low attaching filler material alloy composition low, Zr _{aTi bNi c} (in formula, each, Zr, Ti and Ni atmoic % to show a, b and c, 47 a 52, 24 b 30, 22 c 26 and 0.3c/(a+c) 0.35 is shown.)So 3 original type alloy compositions of Zr Ti Ni which is displayed, or, Zr _{aTi bNi cCu d} (in formula, a and b, each, Zr, Ti, Ni and Cu atmoic % it shows c and d, 48 a 60, 20 b 28, 19 c+d 30, 3 d 12 and 0.12d/(c+d) shows the 0.5.)So 4 original type alloy compositions of Zr Ti Ni Cu which is displayed are offered.
