COPPER WELDING POWDER
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°Cto 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.
