产品性能：白色晶体粉末，粉末平均粒径在3.5-8.0微米之间,最大的颗粒通过500目标准筛。主成分为KF-ALF二元系低共晶点组成，分子比1.2左右，熔化温度在557-565℃之间。溶解度（20℃，100ml水）：0.28±0.05g，密度2.7g/cm，堆积密度0.35-0.55g/cm。水溶液PH值：6-7。钎剂熔化时清亮透明，高温下有高活性，能很好地破除金属铝铜表面的氧化膜，使钎料铺展湿润，通过毛细作用钎料被植入钎缝中，常温下钎焊后玻璃状残渣不溶于水，不吸潮，无腐蚀。特别是在氮气保护下钎焊，钎剂用量少，焊后可不清洗，使用方便，显现出强大的优越性。

适用范围：应用于铝-铝、铝-铝合金、铝-不锈钢等钎焊中，本产品广泛适用于汽车空调、铝蒸发器、铝散热器、电热电器、铝合金结构件等行业。产品包装：袋装，内塑外编，每袋净重25公斤。桶装，内塑膜，外纸桶，每桶净重40公斤。

AL-FLUXPotassium Fluoaluminate

IN recent years, method has been widely used in zhe brazing process of aluminium and its alloys.The product introduced here is just the brazing agent used in the brazing process.

PROPERTIES: white crystal powder ,average particle size 3.5-8.0μm ,and all through 500 mesh sieve; composed by KF-ALF, Molecular rate near 1.2,melting point 557℃~565℃.solubility in 1000g water at 20℃is 0.23-0.33g/cm,density:2.7g/cm,bulk density:0.35-0.55g/cm.PH value in water:6-7.It is clear and transparent while melting and highly active under high temperature; It can get ride of ALO coating on AL surface to make the brazing agent spread evenly and wetly. It also has good joint filling property through capillary. under normal temperature, after brazing, the glass-like residues is insoluble in water,nonhygroscopic,non-corrosion and demonstrates completely inactive. The usage quantity of thin brazing agent is quite less, especially when braze under the protection or Nitrogen. It doesn’t need to be washed after brazing and its usage is convenient, which showsits great advantage. APPLICATION: widely used to braze al-al,al-al alloy and al-stainless steel in process auto air-condition,al radiator,e-boiler and al alloy components etc.PACKING:in 25kgplastic woven bags or 40kg fibre drums with film lining
