Be clean.

That's really with only very fine (dry) powdery type mixtures. It
won't be a problem with a saw. Your clump just bonded because of

the mixture of iron and aluminum powders is called "Thermite".

Actually it's the mixture of aluminum (fuel) and iron OXIDE or rust (as
the oxidizer) that's called thermite.

I don't believe the ground AL and FE will do squat until the latter
turns to rust and the temperature is run up to around 600+ degrees.
