scroll saw on aluminum?

Any blade that will cut wood, will cut aluminum. I cut great quantities of aluminum on my machinery. Table saw with carbide, chop saw with carbide, band saw NOT carbide, jointer NOT carbide, with and without carbide. I can't say it dulls the blade any more or less than wood, but probably less as there is no grit or impurities in the aluminum.

aluminum cuts very nicely with a scroll saw.I did that a few times.

I cut out a couple of pickguards for heavy metal guitars. They were thin aluminum diamond plate, and I used a Shopsmith scroll saw, worked just fine.

Use a bit of blade wax lube. Wood blades cut ally just fine but ally can gall the gullets while sawdust does not. A bit of lube can prevent that.

Aluminum across a jointer?

Wes

Yes, in thin cross-sections. I've often sandwiched a sheet of aluminum between wood, and used all the standard tools for finishing a layout: Table saw, router, jointer -- the whole works. I used to do it several times a year with 0.063"-6061. I've done it with 1/4", but the feed rates and cutter depth need to be carefully attended to.

Now that I have a big enough mill, and a big enough milling vise, I do most of that on the mill.

Yes, I did not miswrite about the jointer. I did leave out the word router in the next cite, though. Aluminum can be really bad about galling on blades. I have a tube of stick wax and it seems to solve most of the problems.
