Aluminum alloy 4643 is a non-heat-treatable wrought alloy. It is primarily known as a welding filler wire. It contains silicon and magnesium as its main alloying elements, with silicon being the larger component (around 4%). It belongs to the 4000 series of aluminum alloys, where silicon is the primary alloying element used to lower the melting point and improve fluidity for welding applications. Alloy 4643 is particularly recommended for welding thick or heavy 6xxx series aluminum base metals.
