4043 or 5356 better for cast aluminum
What is the best tig rod for cast aluminum? 5356 is stronger than 4043 but tends to get porosity when used to weld aluminum castings. 4043 is fine and usually a pretty good choice for castings because the silicon content makes it a close match for most aluminum castings.
