Brass brazing alloys are known for their various unique features. Brass brazing alloys are particularly adaptable when close fit cannot be held. This filler metal may be used where narrow joint clearance cannot be held. It has the ability to fill wide joint clearances at the lower end of its brazing range. at the high end of the brazing range , it is more fluid. Chemical and physical characteristics of these alloys are shown in table.

brass type special ductile alloy for ferrous and cuprous metals. UTP 1 is particularly recommended for hot-galvanized tubes. Ni containing brass brazing rod for building up on steel,grey cast iron and malleable cast iron against gliding wear. The deposit is also corrosion resistant.High-strength nickel and silver containing special alloy for brazing of butt joints on heavily stressed components in the construction of vehicles and sleeveless pipe assembles. |
