 This work gives an overview of the production, properties and industrial applications of metal phones. First, it classifies the most relevant manufacturing routes and methods. Then, it reviews the most important properties with special interest in the mechanical and functional aspects, but also taking into account costs and feasibility considerations. These properties are the motivation and basis of related applications. Finally, a summary of the most relevant applications showing a large number of actual examples is presented. Concluding, we can forecast a slow, but continuous growth of this industrial sector. This article was authored by Francisco Garcia Moreno.
