Abstract: The present invention provides a solder for nickel based superalloy soldering. The solder includes 11 wt % to 13 wt % chromium, 5.0 wt % to 7.0 wt % aluminum, 3.5 wt % to 5.0 wt % molybdenum, 1.5 wt % to 2.5 wt % niobium, 0.4 wt % to 1.0 wt % titanium, 0.03 wt % to 0.07 wt % carbon, 0.05 wt %-0.15 wt % zirconium, 0.001 wt % to 0.1 wt % boron and remainder nickel or other inevitable impurities, thereby reducing occurrence of soldering hot cracking and insufficient weld bead strength in nickel based superalloy raw materials during soldering.
