There i another aspect to factor in, and that is chipload per tooth (or edge) At 1920 rpm, with 4 flutes, you are presenting 7680 "cuts" per minute. How fast are you planning on feeding the mill? Aluminum, in it's vanilla form like 6061, anything between 0.005 and 0.015 per tooth/flute should be fine, if you have the HP and rigidity. That makes some fast feeding. ~38 IPM
And depending on depth of cut, you may find a blast of air to just keep the chips clear will be enough. Or a climb cut of 0.005 depth will leave a good finish. Lots of variables.
