I am MIG welding 5052 aluminum to 6061 aluminum, both 10 gage material. Can I use 4043 wire for this application, or 5356 since this would match the 5052? Also, does anyone know if there's a problem welding 6061 with 5356 wire? I know 4043 is the best alloy, but the 5356 feeds better. Thanks for your input!
