RBCuZn-B  Nickel Bronze (RBCuZn-B) brazing filler metal is similar to naval bronze but contains manganese and iron which increase the hardness and strength of the weld deposit.  It also contains nickel ensuring uniform distribution of the iron in the deposit.  A neutral or slightly oxidizing flame and a boric acid/boric type flux should be used.
