What case would one be appropriate to use over the other? I dont plan on any furniture or art stuff just repair. Which rod is most useful? Cast iron, building up bushing and wear areas.
 
Aluminum bronze is stronger so better for repairs that need strength. Its also better for salt water and acidic environments. Welds better on AC, so if you have a DC only welder you may be better off with silicon bronze. Silicon bronze flows easier, and has more appealing aesthetics. So if you want the gold color to show for whatever reason, you are probably better off with SilBro. SilBro also works much better on DC. I would use SilBro on any bushing type applications.

There are also dissimilar metal combinations that are better off with one or the other. I don't remember what they are, but you can google the charts on the interwebs.SilBro get used an awful lot for body work, especially in a MIG type application. SilBro is also much better when joining galvanized metal.

Thanks everyone. I'm trying to build my filler rod stock up in order of usefulness. 10lbs of er70s 3/32, 10lbs of er70s 1/16, 5 lbs er70s .045 (which made all the difference between 1/16 filler in .050 sheet metal) , 1 lb 316l . Next is aluminum or silicon bronze. Just chipping away as cash allows. Now I'm out of argon and have to wait a few until I can get a fill up. What other types of filler do you recommend for DC tig welding? Im thinking some 308 will be next.
 
If you are looking to do repair work and you have such an extremely limited budget I would recommend you purchase 4943 aluminum filler before you ever buy silicon bronze or aluminum bronze. Now my recommendation could be inappropriate but based on my understanding of what you are looking to do that is my $0.02.

Is that a rod for welding Aluminum? Please help me understand.

He only has a DC welder. Yes, I know it is technically possible to weld aluminum on DC with pure helium, but a new guy isn't going to do that. So for all intents and purposes, he won't be welding aluminum, and aluminum filler will be superfluous.

That is a good point. I totally disregarded the DC part and just saw the last part based on "next is aluminum or silicon bronze"

It is an all-around rod for aluminum. I completely disregarded the fact that you are only doing DC. My bad.
As you mentioned in your previous post I am broke as a joke. I am now ready to do small repairs. My goal is to get some experience doing small repair and small fab type things and investing back into more equipment. I have grinders, torches, cold cut saw, welder, tools and enough shop space to work. Now I wait here for work to magically fall from the sky.

What color is albr? Does it need A/C or is will DC work? Does it flow
On DC or is it sluggish? Can it braze Al?
I just watched a dude on weld.com weld up a old tractor block with ERCuAl-A2 he used AC and he said he likes AC but he didnt mention anything about anything except he likes the AC cleaning action. https://www.youtube.com/watch?v=iyAykUm_Ykg
 
Forget all that crap for now and become profeccient at steel. We be farting with that , been at this 40+ years and have Never used ita d unlikely to tomorrow. Meanwhile made well north of 100000 welds, 1000's of feet on steel.

You will note that I said aluminum bronze welds better on AC, not that it can't be welded on DC. On DC the aluminum bronze gets like an oxide layer on the surface, almost like a scum layer, and it makes it a bit more difficult to work with. You can do it, but honestly you will have a better time on DC with SilBro.

Sounds like mig aluminum. You can see the oxide particles floating?
