You are probably pushing that cutter a little bit hard. 5x diameter cutting edge is a little bit high, so you will need to back off of it a little bit. You might want to step up the diameter to a 3/8" and step off the WOC a little bit.
I regularly run a 3 flute 3/8" carbide end mill at .375" DOC, .05" WOC, 10,000 RPM, 90 IPM. That is .003 IPT, 1.69 MRR.
I have a video with mine running a .25" end mill with .25" DOC, .035" WOC, at 110 IPM and it is cutting just fine.

Did you have any coolant running? That will be needed for sure if you are trying to push it with aluminum.
I hope that helps.
