The unique combination of properties presented by aluminum and its alloys, make this material one of the most versatile, economical and attractive for a wide range of uses and applications; From the manufacture of aluminum foil to more demanding engineering aluminum alloy applications such as aircraft fuselages.
Aluminum alloys rank second (with respect to steel) in materials that are used for structural purposes. They have a density of only 2.7 g / cm3 (approximately one-third of the steel (7.83 g / cm3)). This very lightweight, together with the high strength in some aluminum alloys, allows the construction of lightweight and resistant structures, particularly advantageous in space vehicles, aircraft and in all types of land or nautical vehicles.
Series of alloys to confirm:
Series 1xxx: Aluminum in 99% purity. It has many applications, especially in the electric and chemical fields. These grades of aluminum are characterized by excellent resistance to corrosion, high thermal and electrical conductivity, low mechanical properties and excellent workability.
Series 2xxx: Copper is the main alloy element of this series. This type of alloys requires a thermal solution treatment to obtain optimal properties. The alloys in this series do not have as good corrosion resistance as most other aluminum alloys.
Serie3xxx: Manganese is the main element of this series. These types of alloys are generally not thermally treatable; However, they have 20% more resistance than the alloys of the 1xxx series.
Series 4xxx: Silicon is the main element of this series. They have a low coefficient of thermal expansion and high wear resistance. An example of this is alloy 4032, used to produce engine pistons.
5xxx Series: Magnesium is the main element of this series. The alloys of this series have good welding characteristics and good resistance to corrosion in marine environments.
Series 6xxx: The alloys in this series contain silicon and magnesium in proportions required for the formation of magnesium silicide (MG2SI). This compound makes them heat-treatable, although not as strong as most 2xxx and 7xxx alloys. They are characterized by their good shape, weldability, machinability, and resistance to corrosion. Such as aluminum alloy 6061, 6005 aluminum alloy, 6063 t6 aluminum alloy.
7xxx Series: Zinc is the main element of this series. The alloys in this series are mainly concerned with fuselage structures, mobile equipment and parts subject to high working voltages.
Series 8xxx: Alloys with a wide range of chemical compositions. A well-used alloy of this series is 8090. An alloy hardenable by precipitation and has replaced alloys of the series 2xxx and 7xxx in aerospace applications, such as components of helicopters.
