Aluminum-Copper flux cored brazing wire

Aluminum-Copper flux cored brazing wire

The Cu-Al flux cored wire consists of a Zn-Al alloy in strip form that is rolled around a white, powdered fluoride flux. The flux is non-corrosive and non-hygroscopic, It’s used to braze for joining copper to aluminum, brass to aluminum and aluminum to aluminum by flame brazing, induction brazing and furnace brazing. It’s the ideal brazing material for joining copper tube to aluminum tube at pressent in refrigeration industry.
