4004 0.06mm aluminium foil braze welding alloy has low melting point and good fluidity, which is suitable for use as filler metal. The typical aluminum base solders are 4343, 4045 and 4004 alloys. The main chemical composition and properties are listed in Table 1.
4004 0.06mm Aluminium Foil Braze Welding contains magnesium, suitable for use in vacuum brazing. In the process of brazing, the magnesium vapor reacts with the residual oxygen and water in the furnace to play a purification role. The magnesium vapor also inhibits the reoxidation of the brazed aluminum alloy
