Any chance demand from domestic US automakers would increase enough to stem US aluminum industry losses? With higher MPG CAFE fleet requirements, I'd assume a surge in demand for aluminum for vehicle unibodies (which is stronger and lighter than steel).

Also, I'd be curious if aluminum plants might start buying renewables with locked in rates to compete against foreign firms who have access to cheaper energy (utility scale solar is already down to 4 cents/kwh).




The aluminum market is global and generally thought to have too much capacity. Even if US aluminum demand increased dramatically it would unlikely help the US industry much because production cost are cheaper elsewhere.


The Ford F150, which is the best selling vehicle in America, switched to aluminum body panels this year.


Carbon fiber is stronger and lighter than either.


Yes but carbon fiber shards. Aluminum crumples, which is good for absorbing energy and keeping people safe while in a car.


Yep, exactly. Carbon fiber is great for aircraft, not so good for cars.

Just a headsup,a link inside the article about a video of an airplane wing failing has gone bad and now leads to a malware site.


Thanks for the heads up!


The "carbotanium" (bonded titanium and carbon composite) of the Pagani Huayra is supposed to get around some of the problems of using carbon composites in a car.

Not exactly cheap though...


Also the glues in carbon fibre are probably not ideal in the event of a fire.


Also way more expensive.


Not if the price of aluminum is falling as quickly as it is. Thanks China!

EDIT: I replied to the wrong comment. My apologies!


Er, carbon fiber is the more expensive one, by a huge margin. A falling price of aluminum just makes that worse!

Edit reply: wrong comment makes more sense! Well, I'll let this stand in case anyone doesn't know that carbon fiber is expensive.


Carbon fiber can't be recycled.


You can burn it!
