Filler Alloy Selection For Aluminum Welding

This alloy group is easily welded with the high magnesium filler alloys such as 5356, which ensures the weld contains sufficient magnesium to prevent cracking. Silicon based filler alloys such as 4043 are not generally recommended for these alloys because the excess Si introduced by the filler alloy can result in the formation of excessive amounts of brittle Mg2Si particles in the weld.
