4004 H18 aluminium foil for vacuum brazing

4004 H18 aluminium foil for vacuum brazing of aluminium base filler metal and aluminium alloy braze plate. During brazing, the brazed material does not melt, and the filler metal melts and fills the joint to connect the workpiece. Aluminum alloy brazing plate can be made by coating aluminum base filler metal on aluminum alloy core material, which is widely used in manufacturing heat exchanger.


 
4004 H18 aluminium foil for vacuum brazing 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.

4004 H18 aluminium foil for vacuum brazing 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
