Wide application of aluminium in industry is mainly explained by its large natural resources as well as a set of chemical, physical and mechanical properties.

Aluminium is one of the most widespread metals, regarding its content in the earth's crust (~8 %).

Among one of aluminium’s advantages shall be considered its low density (2.7 g/cm³), relatively high strength properties, good thermal and electric conductivity, technological effectiveness, high corrosion resistance. Due to combination of these properties aluminium is considered to be one of the most important engineering materials.

Aluminium alloys are the main structural material in aircraft industry at the present-day stage of subsonic and supersonic aircraft development. Alloys of 2ххх, Зххх, 5ххх, 6ххх and 7ххх series are widely used for aircraft industry in the USA. 2ххх series is recommended for work at high operating temperatures and with increased values of fracture toughness ratio. Alloys of 7ххх series are recommended for operation of significantly loaded parts at lower temperatures and for parts with high corrosion resistance under stress.
