Aluminum is one of the most demanded metals since its industrial
production. Due to its lightweight, durable and malleable metal to
various types of processing, aluminum rolled metal has become a raw
product in most spheres of human activity.
The main advantages of aluminum:
High thermal and electrical conductivity
On the basis of aluminum, various alloys are obtained, the properties of which depend on the alloying elements.
Aluminum and aluminum alloys are classified:
High strength alloys
Corrosion resistant alloys
Marine or ship alloys
The properties of various alloys can be conditionally divided into technological and operational. The technological properties of the alloy determine the method of its processing, and the operational properties are the main criterion for choosing a material for a particular part. However, these and other properties do not always coincide with the desired result, since some alloys do not resist corrosion well enough, but they are excellent in mechanical properties.
The problem is solved by plating semi-finished products, i.e. coating the product with a thin layer of pure aluminum. The surface of aluminum under normal conditions in a matter of minutes is oxidized by the oxygen contained in the air and forms an oxide film, which serves as a reliable protection against various types of corrosion.
Methods for rolling aluminum
Due to the wide range of properties of alloys, the production of rolled aluminum is carried out in various ways, namely by casting and deformation. Deformation can be cold or hot and, in turn, is divided into rolling and drawing. In production where aluminum semi-finished products are used as blanks, various processing methods are also used: deformation - forging, stamping and upsetting, as well as machining with a cutting tool. .
