Aluminium-Silicon alloy filler metal used both for brazing and GTA (TIG) welding of aluminium alloys. Suitable for welding Al-Si and Al-Si-Mg cast aluminium alloys, having silicon content of > 7%. Very good capillary flow in brazing and brazed joints are matching structure and colour of aluminium alloys. Suitable for brazing of rolled and cast aluminium alloys. Excess acetylene flame has to be used during brazing. Widely used in production of kettle, frier, solar heaters. Used in combination with BF14 flux in brazing applications.
