Fatigue, and failure modes are unpredictable for a lot of alloys.
Machinability, and masleability is usually going in reverse to strength.
Tempering, and annealing to counter the above add to cycle time, and cost.
Some aluminium alloys cold flow.
Aluminium is generally excellent for corrosion resistance against anything you have in your household, but sometimes it isn't.
You can't weld it.
Few things can stick to it.
It's thermal expansion is much bigger than glass, and steel.
