Yeah extruded alumnium is pretty easy to work with as long as you don't need anything welded. We used 30mm X 30mm Extruded aluminium for all of our robots. There's also 20mm x 20mm Profile that we also used in the previous two years for various parts of our robot to reduce weight. Both of them are very durable, We never hand any problems with it breaking or bending.
