Aluminium processing is an idustrial technique which allows the development of semi-finished plates, sheets and rolls ready for their final use. The industrial aluminium processing can either start from the raw material or from the melting of recycled or secondary aluminium resources. The production of plates and coils is a very delicate technique, which needs to be performed according to the semi-finished product’s final use and desired characteristics. Various manufacturing processes and alloys can be used for aluminium processing depending on the business sector usage.
Aluminium processings are characterized by their extraordinary ductility and versatility, which due to aluminium intrinsic properties and chosen manufacturing phases, can be adapted to a variety of final uses. In fact, with semi-finished aluminium for industrial usage we can produce multilayer tubes and plates for the food sector, automotive, construction and interior design products. Aluminium is characterized by great versatility and lightness, and resistance to corrosion which makes it a barrier for gases, light and humidity. Each aluminium processing can be used to block the trespassing of oxygen and light and increasing resistance, without losing its lightness and flexibility.
Aluminium processing is used for the production of materials in great quantity for industrial usage. Slight percentages of other metals are added to the hot melt aluminium in order to obtain aluminium alloys and semi-finished more adapt to the final use. With aluminium lamination it is possible to reduce its thickness, reaching the desired thinness so to give the right hardness and maneuverability for the final processing. With hot melting, pre-heated aluminium undergoes a mechanic process at really high temperatures. The aluminium block passes through processing rolls until the desired thickness is reached. High temperatures, instead, modify the physical structure of the metal and increase its flexibility. Cold rolling is done at room temperature in order to transform the aluminium sheet and obtain the hardening of the metal. Aluminium processing can be done through various hot and cold rolling processes, until the desired characteristics are reached.
The industrial aluminium processing finds its application in sectors such as light bulbs, supports and capsules fillings, in order to reduce to a minimum the possibility of break during the manufacturing and final usage. Aluminium plates and sheets can be used in different merceological sectors, where resistance to corrosion, thermal conductivity and food preservation are the characteristics needed in order to create a barrier with the outside environment. Semi-finished are used for thermal isolation products, such as tape; where aluminium provides resistance and sealing. Aluminium processing is also used for electric cables, since this metal contains electromagnetic emissions. The production of Honeycomb structures is also part of this processing, as it allows to develop extremely light aluminium panels with an high resistance to compression. The different types of aluminium processings are always defined in accordance with the client on the basis of specific desired techniques and final usage of the semi-finished product.
