Al 4047 filler rod

[67chevelle]

I picked up 10 lbs of 3/32 4047 aluminum filler rod ( 36 inch lengths) 0 at an auction yesterday for $5. One of our LWS sent a bunch of excess inventory to an auction house.

What is this good for? Will it work for Tigging 6061?

After doing some reading on various welding boards and suppliers web sites, It seems that 4047 has a higher silicon content than 4043 and several posters say that they prefer it for welding aluminum castings.

hmm.

Mark,
good stuff to use on high silicon castings! keep away from castings with a high copper content though as the weld interface is very crack prone.
good find!

4047 will flow better than 4043. Yes you can use it on 6061. I forget the strength numbers. If you are using it on a critical assembly you may want to check out the strength
specifications.

4047 is awesome for repairing cracked import aluminum castings, especially
lawnmower transaxles.

wets out very well .

very good find
