Aluminum is a very light metal with a specific weight of g/cm 3, about a third of that of steel. This cuts the costs of manufacturing with aluminum. Again, its use in vehicles reduces deadweight and energy consumption while increasing load capacity. This also reduces noise and improves comfort levels. Its strength can be adapted to the ...
