copper brazing welding flux with less smoke, good fluidity
As a common copperbased brazing flux, featuring less smoke, good fluidity, and even tiny granule, QJ 301 flux could be used for brazing of copper and copper alloy, steel and stainless steel, and hard metal within 850°C to 1150 °C.
QJ302 is a our new developed type of solder paste gathered from all the advantages of the domestic and foreign. QJ302 is better than other brazing flux in fluidity, and permeability, and avoids the problem of fluidity and moistureabsorption. QJ302 paste is used for brazing of copper and copper alloys, stainless steel, carbon steel, hard metal within 850 to 1150 Celsius degree .
It can meet the requirement of high process and automation.
