Should I use 4043 or 5356 filler alloy?

March 26, 2014

As a basic description we can say that 4043 is an aluminum filler alloy with 5% silicon added and that 5356 is an aluminum filler alloy with 5% magnesium added. There are some misconceptions within the industry that you can successfully weld any aluminum base alloy with either 4043 or 5356 filler alloy. I must start by saying that this is not the case. However, there are many common structural aluminum base alloys that can be welded with either 4043 or 5356. One such alloy is 6061.
