Ok well, it's a good grade to cut, not so sticky. However, your cutter is quite long and being straight flutes not ideally suited to aluminium. The stick out will have a large effect on feeds and the straight flutes won't clear chips very well. So I'll say it again because cannot stress enough how important it is to clear the chips away, lots of Air and occassional spray of WD40 will be needed.

Given these new details, I would start with halfing those settings I gave before and work up changing one setting at a time to see the effect. 1st I would play with RPM, then Feed then DOC.
