4047 aluminum clad brazing sheet

Introduction of 4047 aluminum clad brazing sheet
4047 aluminum clad brazing sheet belongs to one of the 4 series alloys. The 4 series aluminum alloy is an aluminum alloy with silicon as the main alloy element. Most alloys are heat-treated non-strengthen aluminum alloys, which refer to alloys containing Cu, Mg and Ni , And when certain elements are absorbed after welding heat treatment to strengthen the alloy, it is possible to strengthen by heat treatment. Due to the high silicon content, low melting point, and good fluidity of the melt, this series of alloys will not produce brittleness in the end, so it is mainly used to make additive materials for aluminum alloy welding, such as brazing welding plates, welding rods, and welding wires.
