I know that where strength is a factor, steel wins outrightThat is why it is used in construction of railways, bridges, ships, and also for nails, rock-breaking machinery, gas turbines, spacecraft(titanium steel), etcI should think that aluminium would beat steel wherever weight was a factor, especially in fueled vehicles since a lighter car gives much better mileageHowever, I've noticed that steel is still preferred over aluminium for car bodiesIs this trend changing? If not, why? I know that aluminium is more expensive than steel but in the long run doesn't the saved fuel make up for it?
the system that is out there is so old that you can build a better model but how can you convience the mega-monster corporation to stop for anything ever? they already got all they ever need to make a buck figured and don't want to stopretooling a can manufacturing company could be a looser just to the employees to the millions of reasons that can come from if somebody get an idea how at what point does the world stop and deal with it polygons are adding corners not cost effective
If you made a car body of aluminium, the slight reduction in body weight would not make an appreciable effect in fuel savingIt is the shape of the body and its streamlining that determine the fuel economy, particularly with high speeds.
