产品名称:Aluminum flux
EL3000Aluminum flux
Product characteristics
High activity flux. It is suitable for brazing process of automobiles air conditioner, intercooler, condenser, evaporator, water tank and various aluminum radiators.
Product advantage
● quickly and effectively remove the oxide film on the surface of aluminum parts and reduce the surface tension of base metal;
● the particle size of the powder is moderate, which is not easy to settle;
● good wettability, fluidity and stable brazing quality between flux and base metal;
● The composition of the flux is close to the eutectic point with low melting point;
● comply with ROHS environmental protection requirements.
Application scope
Suitable for brazing of aluminum and aluminum alloy. It is applicable to all kinds of brazing methods such as gas protection furnace or low temperature flame, brazing pure aluminum, aluminum manganese and other alloys. The brazing surface is bright and clean without blackening, forming uniform film, corrosion-free and anti-corrosion and anti-oxidation, non-toxic, tasteless and pollution-free, long-term storage without moisture absorption and agglomeration. The melting temperature of noncorrosive aluminum brazing flux is relatively narrow, about 550 ℃. Especially at present, most of the domestic automobiles air conditioners, aluminum condensers and aluminum radiators are the most ideal welding solvents.
