AlcoTec Filler Metal 4643 is a reduced-silicon, magnesium-added filler metal used to weld the 6xxx series alloys. Welds meet the high mechanical properties of the 6xxx series, particularly in multipass welding and when low dilution exists. There is no advantage in using 4643 compared to 4043 or other filler metals when no heat treatment is done after welding. The corrosion resistance is very good. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as joining. Filing Code: AL-324. Producer or source: AlcoTec Wire Corporation. Originally published August 1992, revised March 2002.
