I need a bit of ally plate, preferably a 24" equilateral triangle or a two foot by two foot square, I need it sharpish Half inch thickness, who is my best bet, please don't suggest the aluminium warehouse.

This would be my first go too, once got a bit cut out of an 8x4 sheet of billet and inch thick.

Or possibly Aalco

All depending on the grade you want.
