铝焊剂ASSTY 本产品是具有非吸水性和非腐蚀性等特点的氟化铝钾（Potassium Aluminum Fluoride盐）焊剂。用于惰性气体（Nitrogen）环境中的钎焊，焊接后形成同样属于非吸水性和非腐蚀性的焊剂残渣膜。钎焊性能优秀，可用少量的焊剂，得到良好的效果，在钎焊的材料表面不残留焊剂残渣，外观干净美观。 铝焊剂的化学成份和物理性质 品名 项目 ASSTY(AF-1) 化学成份 K(%) 26~34 AL(%) 15~20 F(%) 46~59 性质 比重(S.C/20℃ : 5%) 1.035±0.01 熔融温度(℃) 560~578 平均粒度(?) 6~12 熔融面积(?/㎎) 0.25up 外观密度(Bulk Density : g/?) 500~750 * ASSTY是（株）JC生产的焊剂的专有商品名称。 Category Item ASSTY(AF-1) Chemical Composition K(%) 26~34 AL(%) 15~20 F(%) 46~59 Physical Properties Specific Gravity(S.C/20?? : 5%) 1.035±0.01 Melting Temperature(??) 560~578 Average Granularity(??) 6~12 Melting Area(??/??) 0.25up Apparent Density(Bulk Density : g/??) 500~750 This product is a Potassium Aluminum Fluoride based Flux， with moisture absorption and corrosion protective characteristics. It is used for brazing under a noble gas (Nitrogen) atmosphere， and the remnant coating film of the flux formed afterward also has moisture absorption and corrosion protective characteristics. It has the excellent effects of brazing characteristics with the use of only a small amount， and creates a clean appearance without any flux powder remnants on the material.
