Certain saws produced are capable of cutting aluminium. However this must be checked in the instruction manual of the saw, if the saw is capable of cutting aluminium it would require a blade specifically designed for cutting non ferrous (soft) metal, otherwise, the saw will be placed under too much strain for it to operate effectively.
Saws that can be used:
Some Portable Circular Saws,
Some Mitre Saws,
All must be used with Non Ferrous metal cutting blades.
