Product Description
Alloy Type: A5.3, ALUMINUM AND ALUMINUM ALLOY Covered Arc Welding Electrodes
E4043 is a general purpose aluminum electrode for arc welding aluminum alloys. The arc is stable and operates at low temperatures with a minimum of spatter and fuming. The welds are strong, dense, and free of porosity on both production and maintenance applications. E4043 is a great choice when welding heat-treated aluminum parts. This welding rod may also be used in brazing applications.
Typical Applications: arc welding aluminums alloyed with copper, silicon and manganese, excellent for joining dissimilar grades of aluminum
