Metal processing What is a Metal ? Structures of Metals . Metal Properties . In industry, molten metal is cooled to form the solid. The solid metal is then mechanically shaped to form a particular product. How these steps are carried out is very important because heat and plastic deformation can strongly affect the mechanical properties of a metal.
The disadvantage is that there has to be an additional process step, furthermore the electrical properties change because the doped regions are enlarged. Instead of pure aluminum an alloy of aluminum and silicon can be used (silicon 1–2 %). Because the aluminum now already contains silicon there will be no diffusion out of the substrate.

Aluminum, titanium, iron, and nickel—these are the building blocks of modern society. Without the raw materials trapped in the earth’s crust, and the technology to extract and process those minerals into various alloys, humans would still be living in grass huts and chasing their food with wooden clubs.
Diffusion is a process in which atoms or molecules move across a boundary between two contacting materials. Ion implantation produces a similar result, but the process involves penetration of high-velocity ions into the surface of a substrate material.
Passivation is a widely-used metal finishing process to prevent corrosion. In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely
