EL3000Aluminium flux

Product features
High activity flux.  It is suitable for brazing of automobile air conditioners, intercoolers, condensers, evaporators, water tanks and various aluminum radiators.
Product advantage
● Quickly and effectively remove the oxide film on the surface of aluminum parts to reduce the surface tension of base metal;
Low powder particle size is moderate, not easy to settle;
● Brazing agent has good wettability with base metal, good fluidity and stable brazing quality;
Low solder composition close to eutectic point, low melting point;
● Meet RoHS environmental protection requirements.
Application range
Suitable for brazing aluminum and aluminum alloy materials.  It is suitable for various brazing methods such as gas shielded furnaces or low-temperature flames. The brazing surface of pure aluminum, aluminum manganese and other alloys is bright and clean, does not blacken, forms a uniform thin film, has no corrosion and corrosion resistance and oxidation resistance, is nontoxic, tasteless and pollution-free, and does not absorb moisture and agglomerate after long-term storage.  The melting temperature of non-corrosive aluminum brazing flux is relatively narrow, the temperature is about 550℃.  Especially at present, most domestic automobile air conditioners, aluminum condensers and aluminum radiator furnaces are ideal welding solvents for welding.
Parameter

Use method
Application process: welding in protective atmosphere furnace
Welding temperature: 550 ~ 680℃
Brazing flux/water = 1/10-20 (weight ratio) is painted or sprayed on the surface of the workpiece, and then the workpiece is welded in the furnace.
