An ordinary wood mitre saw will wass thru this alloy section with no problems.
Nice clean cut and square.

You will need to clamp it to the back fence, don't rely on just holding it and use goggles and a smock / overalls or something as the chips come keen on your arms.

I have a real simple one from Aldi, I think it was £19.99 and it makes brill job but I did fit a finer blade, again from Aldi, two blades for a tenner.
