Rolled aluminum is widely used as a structural material in industries such as automotive, shipbuilding (using a special marine aluminum), nuclear engineering, and railroad car manufacturing, aerospace, petrochemical, food and medical industries as well as in the production of household appliances. The construction of the aluminum rolling increases the durability and reliability of structures - aluminum beam has no equal in the ratio of lightness, strength and cost. It is widely used for the construction of suspended structures, supports. In addition, it is used in the design for the decorative finishing and decoration.
Pure aluminum has a relatively low strength, so it is used in most cases in the form of different alloys, often alloyed with copper, silicon, zinc, manganese, magnesium, or combinations thereof.
Aluminum metal is corrosion resistant, has a high electrical and thermal conductivity, heat resistance and ductility. Aluminum lends itself to hot and cold processing (pressing, drawing, stamping, forging and rolling) and has a low weight.
Depending on the method for producing aluminum alloys are subdivided on the deformable (manufactured semi finished: sheet, rod, profile, pipe, bar) and casting (using a crucible for the aluminum, in which the melt after - casting in forms commonly used recycled output is obtained product or ingots / bar).
By heat treatment are thermally hardenable alloys (e.g., duralumin, alloys of Al-Cu-Mg) or a thermally hardening (e.g. AMts alloys AMg2, AMg3, AMg5, AMg6 etc.).
Aluminum metal is also divided, given the scope of its use, for example, aviation, marine, food. The use of aluminum in the first two Ferah due to its lightness, as in aircraft and ship building is an extremely important factor in weight that determines the performance characteristics of the product. Aircraft aluminum used in the creation of spacecraft parts: fasteners, brackets, containers, chassis and housings. Today, the proportion of aluminum in the dry weight of a conventional passenger aircraft is 2/3 - 3/4 and 1/20 of the rocket - 1/2.
