4004 aluminium braze welding foil

Introduction of 4004 aluminium braze welding foil

4004 aluminium braze welding foil belongs to A1-Si series aluminum alloy. The main components of the alloy are: w(Si)=9.0%~10.5%, w(Mg)=1.0%~2.0%. Wetting, fluidity and corrosion resistance have an effect, and magnesium is a metal activator and getter. The alloy has low melting point, good melt fluidity, and easy feeding. It is mainly used for brazing sheet materials of aluminum alloys.
