Aluminum has become a wonder-material for some carmakers. And why not? An aluminum-bodied car has the potential to improve fuel economy, crashworthiness, and handling. On the downside, it’s expensive, difficult to weld, and its dings and dents aren’t as easily hammered out by your local body shop.
Can cars be made with aluminum?
Ten years ago, aluminum was only used in exotic and luxury cars, but now many mainstream cars have aluminum hoods, doors, and trunk lids. Aluminum is also gaining favor as an engine block material, taking cast iron in many vehicles.
Is aluminum a good material for cars?
Above all, aluminum is a lightweight material. When used in automobiles, it can significantly enhance performance and improve fuel economy. Not only that, but aluminum is strong. It is because of the strength-to-weight ratio that aluminum is so valuable in the transportation industry.
What is the disadvantage of using Aluminium in vehicles?
Aluminum is far more expensive than steel in a raw state, in its conversion to a usable sheet metal, and in its assembly. This results in a 60 to 80 percent cost premium. Therefore, aluminum cars are more costly to produce than those made from steel.
