Brazing flux powder for copper to copper  

As a common copper based brazing flux, featuring less smoke, good fluidity, and even tiny granule,HZ-QJ301 flux could be used for brazing of copper and copper alloy, steel and stainless steel, and hard metal within 850°C to 1150 °C. 

Operation: 

One option is to make the powder mixed with hot water to be creamy, While the other option is to dip the filler metal wire in the powder. Operator should try not to heat the filler metal and the flux directly by the flame.

Post treatment: 

The residue is glassy solid attached on the work pieces. Usually it can be sanded off. The more convenient method is to merge the hot work pieces into cold water after the solidification of the filler metal. The residue can fall off the surfaces because of the sudden boiling of water. Partial component in the residue can be dissolved into the water. In this method, the temperature difference between the cold water and the work pieces should be cautiously controlled to prevent the shaping and cracking of the work piece.

Application: 

suitable for the factory of radiator, bike, fitness apparatus, refrigeration accessories, automobile accessories, ornaments and jewelry, electric equipment, hardware tool etc.
