Pure aluminum is significantly soft.  That is why it is almost always
alloyed with other materials to bring the hardness up to an acceptable level
on the Brinell, Vickers or Rockwell scales based on what it will be used
for.

The other problem may be that the tool you were using was obtained from
Harbor Freight...  Hi, Hi.

Hi People,

I was doing fine cutting the slits in an aluminum tub until the fiber blade
made for cutting metal wore down to small to continue.  This was a blade
that came with my RotoZip tool.  I thought Aluminum was supposed to be soft.
I had four of these slots to cut and I got maybe  1 and 1/3 slots cut.
