Ford Aluminum Body

There are lots of alloys of aluminum and while it is correct that the aluminum used in aircraft is not very corrosion resistant many alloys are. I have a 40 year old aluminum canoe in my barn right now with no visible corrosion, a 12 year old horse trailer with the 90% that is aluminum in mint condition while the 10% that is steel is rusting and my brother just took a 1956 Feathercraft boat to the river to pull skiers and it is in great shape. I don't expect my aluminum truck body to rust and as much as I hate to admit it I have put several scratches in the paint but at least none have corroded so after 2 years. Aluminum absorbs more energy when bending than steel so your odds of surviving a wreck in a car with lots of aluminum is better than in an all steel car even though the car itself may suffer more damage. Yes, aluminum is more likely to burn but anybody in the truck at that point probably wasn't going to survive anyway.
