Welding Electrode 4043

ER4043 is a versatile aluminum silicon welding wire. Deposited metal has a good resistance to
thermal cracking and also to ensure a certain degree of mechanical properties. However, in the
case of anodizing, the weld metal and the base metal have different colors.
Welding can produce brittle Mg2Si in the weld of aluminum-magnesium alloy, which reduces the plasticity and corrosion resistance of the joint.

Deposited Chemical Composition %(Typical)



Welding Electrode 4043 is a coated electrode designed for maintenance welding of aluminums and aluminum alloys, such as 5454, 5154,  6052, 6063,  700 series.- The proper choice of aluminum filler metal mainly depends on the base metal properties to be achieved and Welding technique.  Post weld cracking, corrosion resistance and behavior under elevated temperature also need to be taken into consideration.
