how thick's the thing you're cutting?
coarse is always good for aluminium to stop the blade clogging, but not too coarse.
for steel i think the rule's something like 3 teeth + on the workpiece

18TPI for tube, 14 for thicker plate otherwise they just clog up.
You should have more to have 3 teeth in contact, but there we go

A good trick when filing aliminium is to rub talcum powder on the file before filing. When the teeth get clogged full of the ali just give it a tap
and all the ali falls out

Or rub a stick of chalk along the file - same effect.
If you're not going to paint the piece (or are prepared to do some clean-up afterwards) then a squirt of wd40 is very helpful.
