Sorry, I think I misunderstood. All aluminum can be used for general aluminum things, but only the aluminum from the extractor byproducts can be used to make the alloy, and I was asking if that could be generalized. It would mean you wouldn't need the extractor before making the performance engine, but I'm not sure how big of a deal that is, compared to the extractor being needed for tungsten and generally valuable anyway for the multiplication.They already are all OreDicted together.
I got a chest full of lapis blocks getting way more aluminum than I needed. Thankfully Extra Utilities + microblocks lets you turn them into walls or fences.
Unrelated feature request: I would appreciate if the details for redstone interaction were more explicit. The industrial coil, for example, doesn't mention at all that it outputs a signal based on its charge. I learned that from the wiki, and then was super frustrated and struggling, with two of them blowing up (and holy wow that's a big crater they leave!), before I realized the need for the redstone comparator properly positioned.
That example was majorly compounded by my ignorance of redstone in general, of course, but extra information is always appreciated in-game. I dislike using wikis, and for that reason really love the books you've included (and NEI, may we never go back to the bad old days before that!).
