Abstract
A vertical casting process for an intermediate product, including the steps of (a) preparation of at least two aluminum based alloys, particularly a first alloy with composition P and a second alloy with composition T, (b) casting of the first alloy with composition P to a required height H, and (c) casting of an additional required height Hof the alloy with composition T. The object of this invention is the manufacture of monolithic structural elements with working properties that are variable in at least one direction, and particularly bi-functional or multi-functional structural elements capable of performing at least two functions that are traditionally performed by two different parts.
