From an aircraft mechanics point of view, high strength aluminum is not easily bent without cracking. Depending on the alloy involved and the heat treatment.

6061-T6, a common sheetmetal alloy in aircraft use will not make a sharp 90 degree bend without cracking. If I use a gentle radius, I can bend it through 90 degrees. However, 6061-T0 will bend to nearly any shape required without much risk of cracking. It can then be brought to a harder condition after machining.
