Not even close to "exceptionally dangerous". As far as the table saw is concerned, its just a less dusty wood, follow standard safety precautions and the danger is the same as any other cutting operation. Secure the work, keep your hands away from the blade, avoid kickback situations, etc.
They are about 1" strips of aluminum about 24" long with rounded edges.
I was wanting to square an edge or possibly make sled runners for band saw table.
You know, goofy stuff that you just try to create while in the shop that might not be a good idea in the end.
I guess it would be the same blade that I would use to cut T Track on miter saw.
As other people have already said, you can cut aluminium with a standard woodcutting blade, you dont need anything special. Frankly as far as the tool is concerned, aluminium is just a slightly harder and less dusty species of wood. Carbide tools cut it just fine, you can actually route profiles on the edge of a piece (though that does get admittedly dicey). Heck, if you wanted to you could actually use a hand plane and plane a chamfer on the edge of an aluminium bar. Have to sharpen your blade a bit sooner, but its possible, and ive done it. Standard common sense applies, make sure your workpiece is secured from unintended movement, keep hands away, dont force-feed the work, and watch out for the chips, they come off hot
Now, for your particular use, i.e sled runners, table saw wont work. Itll cut, but not particularly well. Cutting aluminium on the table saw, especially ripping, leaves pretty rough edges. The blade deflects, the cut wont be straight, and aluminium really likes having some sort of cutting lubricant to prevent galling which you cant really do on a table saw. Youd end up with a saw runner that might be close to proper dimension, but with a sloppy fit that doesnt slide smoothly
