- By Frank Armao
- Dec 30, 2014
- Aluminum Welding
- Article
Q: I usually use 4043 filler wire for welding 6061-T6 and castings. My friend told me I should switch to 4047 because it’s stronger. Is that true? It’s more expensive than 4043. Is it worth it? A: As you know, 4043 and 5356 are the most common aluminum filler alloys. In fact, these two alloys...
