Item # BrazeIt 50N

Primarily used for the brazing of tungsten carbide to steel, this alloy also offers good wetting characteristics on stainless steel, tool steels and nickel alloys. the 3% nickel content provides good corrosion resistance.

Brazeit 50N is a modification of Brazeit 50. It was originally introduced because of somewhat better corrosion resistance than Brazeit 50 for certain conditions, and is still used for such purposes. It has proven successful on many marine applications and for dairy equipment which must withstand strong cleaning solutions. The 3% nickel content of this alloy also improves its wetting of stainless steel and tungsten carbide tool tips. At the present time, the largest use of this brazing alloy is for attaching carbide cutting tips to tool shanks.

When melting, Brazeit 50N passes from the solid state to a mushy or plastic range and progressively to a liquid. The largest portion of Brazeit 50N melts in the upper section of its temperature range. Therefore, the alloy has a good body while in the plastic range and is suitable for building fillets or bridging large gaps. Late melting of the major portion of the alloy also helps minimize any separation of the solid and liquid portions by liquation during melting.

Universal alloy for the brazing of carbide tool assemblies. Nickel addition improves corrosion resistance in marine environment and caustic media.

Standard forms of Brazeit 50N are brazing wire, brazing strip and brazing preforms.

Brazeit 50N contains cadmium and therefore upon heating may produce toxic fumes. It is essential that adequate ventilation be provided so that personnel will not inhale gases and fumes while brazing. The operation and maintenance of brazing equipment of facility should conform to the provisions of American National Standard (ANSI) Z49.1, "Safety in Welding and Cutting." For further information refer to the Material Safety Data Sheet for Brazeit 50N.
