I very often use the same tools as used on aluminum on steel and never have seen any reaction, nor would I ever expect to. The cut materials are much too coarse to ever interact and in any case steel/iron isn't what is mixed with aluminum powder - it's the iron oxides Fe2O3, etc. I have heard from some knife makers that they managed to get some grindings to ignite, but there the products were finer and often left long enough and wet enough to oxidize. But that was a pretty rare occurrence.
There is a reason not to use tooling used on steel on aluminum: it's usually significantly duller after cutting steel. A nice fresh cutter will cut cleaner, chatter less and require a lot less force.
