Hot Max brazing flux powder is for all types of steel, malleable and cast iron, galvanized metals, brass, and bronze. This flux is used for flame brazing with either an oxy-acetylene or electric carbon arc torch. Active Temperature Range: 1400 to 2200 F (760 to 1205 C). Meets AWS A5.31-91 Type FB3J Standards as well as MIL-F-16136B, Types A and B Standards. Made in the USA. Standard Brazing techniques: Clean base metal thoroughly to remove any contaminates. Dip end of filler metal into the flux. At active temperature the flux liquefies and flows into the joint, removing surface oxides and tarnish. Continue heating until the filler metal melts and fills the joint. Flux residue is soluble in hot water.
