I use a 2000W B&Q mitre saw with a 80T or 96T TCT blade for aluminium. Not used it thicker than 16mm so far, but will cut 200mm wide on the slide. Use some WD40 as a lube; gives a better cut. Only downsides compared to a bandsaw are: the noise; the 3mm kerf; throws chips all round the shop despite the 'dust collector' and my Henry on full tilt; oh, did I mention the noise? Ear defenders and goggles a necessity! I made a simple additional clamp as the one for wood that comes with it is too far from the cutting point to be safe.

I will be looking to put a speed controller on it as really it spins too fast for metals...
