Remember Al expands on heating - and you will be hearing as you
cut or mill on it - thereby cutting off or milling off more than you
plan. The metal will have to be flooded as you cut - to keep cool and
make the cut in the right place.



I think you need to specify a temperature range in which you're
interested. IIRC Antimony expands slightly when it solidifies and that
feature is useful in getting better definition in some white metal
casting alloys like modern tin based pewter. Overall though it expands
on heating over the broader temperature range.
