The silicon content of the two is not the same :4043 is mostly used for xenon arc welding 4047 is higher in general 4047 is often used for flame welding or xenon arc welding aluminum welding wire 4043 and 4047 the difference between copper belongs to the aluminum silicon wire series

                Aluminium welding wire

                Lamprophyre is a kind of welding wire which can be brazed directly by flame or induction. Aluminum aluminum welding wire is also known as aluminum aluminum

Flux cored wire, so a kind of welding wire can be aluminum and aluminum welding together named. It is different from ordinary aluminum welding wire to use xenon arc welding machine welding, also different from aluminum silicon welding wire 4047 needs to be welded with brazing agent but only through flame or induction can be directly brazing welding (because of its own brazing agent, so

To do not need additional brazing agent). The welding wire welding out of the workpiece tensile shear strength (joint fastness is not lower than the base material), electrical conductivity, corrosion resistance is good and stable quality, the soldering agent composition and performance of the wire see the site. Compared with aluminum wire welding using xenon arc welding machine, aluminum wire welding workers have simple operation, simple welding equipment, welding will not change the structure of the base material.
