What grade of aluminum is it? The common 6061-T6 doesn't take to bending well. That's a job for 5052 or other. You can bend 6061-T6 if you pre-heat it, but I'm ignorant about how much heat.
Fixing the cracks you have isn't easy and may not be worth the effort. TIG welding would be the better choice, though tedious and expensive.
