Brass Bearing Brazing Alloys

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.
