Re: where can i get strong light AND CHEAP!!!! materials????
The best material is not neccesarily the one with the best strength to weight ratio as people have pointed out. Aluminum is not actually significantly stronger (per weight) than steel (in fact, its significantly weaker than the strongest steels), the reason that it is so popular is that it is easier to create more efficient designs out of aluminum because of its low density and ease of machining. In certain cases, this may even be true for wood.
