Item # BrazeIt B-72
Brazeit B-72 is the eutectic composition of the silver-copper system. It is suitable for use in a controlled atmosphere brazing without the use of a paste flux. When molten, Brazeit B-72 is very fluid and may flow out over the work surfaces during some furnace brazing applications. The wetting action on ferrous metals is limited, minimizing its use on carbon steel. Improved wetting observed when furnace brazing of stainless steel with silver-copper brazing alloys. Most applications for this alloy are on copper and nickel base alloys.

Typical applications are the brazing of ferrous, nonferrous, and dissimilar metals and alloys with close joint clearances.
Good for atmosphere and vacuum furnace brazing of ferrous and non ferrous. Used in critical electronic and aerospace brazements.
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 or facility should conform to the provisions of American National standard (ANSI) Z49.1, "Safety in Welding and Cutting."
