Basic purpose of this lecture is to present on Metals in Industry and working with metals. This lecture part of educational course. Here briefly focus on Metalworking; it is the process of working with metals to create individual parts, assemblies, or large-scale structures. Titanium is a strong metal used in planes, replacement hip joints, bikes etc. Aluminium is a fairly reactive metal that doesn’t corrode due to forming a thin layer of aluminium oxide.
