Traditionally the so-called “Metallurgic Industry” concerns, first of all, the “production of metal items” even if it seems to be more and more difficult to identify a clear separation between this kind of industry and the cars ones because these two sectors use very often to merge into each other. In fact they are often mentioned together in statistics and all the workers and employers of this field belong to the same industrial associations. It is possible to distinguish the concept of “Metallurgy” and of “Siderurgy” considering two parameters: on one hand considering the products typology- raw and semi-finished materials or finished products (tools, locks) – and on the other hand considering materials nature (iron, steal, non-ferrous metals, light metals). In the metal works domain, it is possible to mention three fundamental categories:
1.The Iron and Steal Industry: steal has a great importance. Its applications are innumerable just like the huge variety of production methods that characterize it: without the existence of a great quantity of low cost steal, the Industrial Revolution would be impossible. As time went by, the steal production techniques underwent a process of improvement and specialization, and so now there are many steal typologies and everyone of them is connected to a specific planning and market need. Nowadays modern industries produce more than one billion steal tons par year. All this material is successively destined to be transformed through several production industrial processes such as, for example, melting, forging and moulding. Steal is now very appreciated especially because of its lightness, safety, and strength: all these characteristics are fundamental for many manufactured items. Rust or corrosion can take place on almost all metals. Preventing rust by cleaning, painting, or putting protective coatings on your steel can improve the lifetime by many years.
2.The “Non-Ferrous Metals” Industry: copper represents the most applied non-ferrous metal in industry. Many important alloys such as bronze are based on this crucial material.
3.The Light Metals Industry: Among the light metals, aluminium plays a crucial role compared to the other elements such as magnesium. In fact very often there is the attitude of considering only the aluminium industry.
