產品性能：白色晶體粉末，粉末平均粒徑在3.5-8.0微米之間,最大的顆粒通過500目標準篩。主成分為KF-ALF二元系低共晶點組成，分子比1.2左右，熔化溫度在557-565℃之間。溶解度（20℃，100ml水）：0.28±0.05g，密度2.7g/cm，堆積密度0.35-0.55g/cm。水溶液PH值：6-7。釬劑熔化時清亮透明，高溫下有高活性，能很好地破除金屬鋁銅表麵的氧化膜，使釬料鋪展濕潤，通過毛細作用釬料被植入釬縫中，常溫下釬焊後玻璃狀殘渣不溶於水，不吸潮，無腐蝕。特別是在氮氣保護下釬焊，釬劑用量少，焊後可不清洗，使用方便，顯現出強大的優越性。
適用范圍：應用於鋁-鋁、鋁-鋁合金、鋁-不銹鋼等釬焊中，本產品廣泛適用於汽車空調、鋁蒸發器、鋁散熱器、電熱電器、鋁合金結構件等行業。產品包裝：袋裝，內塑外編，每袋凈重25公斤。桶裝，內塑膜，外紙桶，每桶凈重40公斤。
AL-FLUX Potassium 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
