I cut most aluminum angle and flat bar up to 3/16 in thickness with a hand hacksaw. People sometimes forget how good and accurate a cut you can get if you are careful. Get a good saw frame, use sharp blades that do not wander around and are used only for aluminum, and mark all your cuts carefully on both legs of the angle so you can follow the lines. An accurate machinists combination square set to make the marks is not that expensive and will be useful for the rest of your working days. I did a lot of my compound angles and miters this way but a straight 90 degree cut is pretty easy. Use a good bench vise with padded jaws to hold the aluminum stock steady. (and remember what side of the line you want to cut on). For thicker stuff that is not 20 feet long a table saw with a metal cutting blade works, but you need to keep safety in mind with protective eye, hand and hearing equipment. A cutting fluid helps too.
