Abstract: A method for local forming of a work piece (19) where a force is used for forming a part of said work piece (19) and where a predefined local region of the work piece (19) is heated and that the heated area (6) is formed while the surrounding cooler structure of the work piece (19) is maintained substantially unaffected of the forming operation. A work piece provided with one or more imprints or protrusions made by such method and a tool for performing such method.

Abstract: The present invention relates to mixing raw materials from two or more aluminium metal sources from a Metal Base. The Raw material is categorized ("R", i = 1-n) and stored in a database from where candidate alloys are randomly proposed by a computer and each single Candidate alloy entity is categorized ("C", j= 1-m). Candidate alloys having a CO2 index that is above a set threshold can be discarded for further evaluation. The remaining candidate alloys are further evaluated and qualified with regard to their ability to fulfil the actual functions of use, for instance as a specific product and followingly a set of Qualified Candidate alloys ("QC", k = 1-m) can be defined. The invention also relates to a product produced by the method.
