There are however, important physical and metallurgical differences between steel and aluminum; it is, for instance, much less dense than steel but it is typically used at about 1.5 times the steel thickness in equivalent structural components, e.g. in front rails. These provide the primary energy absorption in a frontal collision and the increased thickness for the aluminum results in more deformation and, hence, enhancement of its energy absorption. Conversely, automotive structural steels will generally deform more before fracturing than the corresponding aluminum materials and therefore the design of components and whole structures must take all such properties and characteristics into account to ensure that the vehicle structures have the requisite crashworthiness.
