Aluminium and its alloys are essential materials in various industries such as aerospace, marine, construction, and automobile. As pure aluminium is relatively soft, small amounts of alloying elements are added to produce a range of mechanical properties. Each alloy has attributes such as high strength, conductivity, and even resistance to environmental effects.

Naming (designator) systems have been developed by the US ANSI / Aluminum Association, ISO & other Standards organizations, to organize them on the basis of their composition (see image). The first digit system of ANSI/AA represents the specific alloying elements and general characteristics of the group, or “series” of these alloys.
Aluminum alloy metals from different series mentioned below are offered as part of our own labelled (AVIATIONEU NEW ERA) product lines in various forms (tubes/pipes, sheets/plates, bars/rods). Sourced from quality producers, they are offered in different cross-sections (for tubes or bars) such as round, hexagonal, square and others, tempers, specifications (depending on the selected product) dimensions/thicknesses, pre-cut or cut-to-order lengths to meet order quantity and application requirements. They can be supplied in pieces or tons depending on the wanted order quantity. For additional information, please refer to the respective sub-categories and product presentations or contact us.

Wrought Alloys Classification
1000 Series
This series is required to have at least 99.00% or higher aluminum purity. It’s characterized by low mechanical properties, excellent corrosion resistance, excellent workability, high thermal and electrical conductivities. Commonly used in the electrical and chemical industries. The the 1100 aluminum plate for the power distribution industry is an alloy example in this series.
2000 Series
The 2000 series aluminum alloy family is a group of "hard alloys" with copper as the primary alloying element. 2000 series aluminum alloys typically contain between 2 to 10% copper, with smaller additions of other elements. The copper provides substantial increases in strength and facilitates precipitation hardening but can also reduce ductility and corrosion resistance. These alloys are known for high performance and excellent strength over a broad range of temperatures but can be the most challenging to weld. They find use in many industries, including the aerospace sector. The widely used 2024 aluminum alloy in the Aerospace industry is a typical example of a 2000 series alloy.
3000 Series
Primarily alloyed with Manganese, these alloys are used as general-purpose alloys and in moderate-strength applications requiring good workability (e.g. in cookware and architectural applications). An example of 3000 series is 3003 alloy aluminum.
4000 Series
Primarily alloyed with Silicon, these alloys feature a lower melting point which improves fluidity when molten. Often used in welding rods and brazing sheets.
5000 Series
The 5000 series are aluminium alloys with magnesium as the primary alloying element. These alloys are readily weldable and feature a high tensile strength and formability, and a good resistance to corrosion in marine atmospheres, making them suitable for use in boat hulls, gangplanks, tanks, and bridges.Also used in a wide variety of other applications including pressurised vessels, buildings and automotive. The 5000 series includes different grades such as the 5052, 5083, 5251 and 5754.
6000 Series
The 6000 series is an aluminum alloy family with magnesium and silicon as their major alloying elements. The remarkable properties of 6000 alloys are their extrudability, excellent strength, and high corrosion resistance. 6000 sereies alloys can also be thermally treated to enhance their strength properties. Extrusion products in the 6000 series are perfect choices for structural and architectural applications and automotive components.
7000 Series
The 7000 series aluminum alloys have zinc as main alloy element (aka zinc grades) and they are the hardest and strongest commercial grades of aluminium, a preferred choice for applications of aerospace, vehicle and high-demanding industries. These alloys feature a higher strength than low-carbon steels and a good wear resistance and weldability, besides, they can also be strengthened by heat treatment. Two widely used alloys in this series are 7050 and 7075.
Temper Designators
In addition to their composition, the alloys can be further classified as non-heat-treatable or heat-treatable, depending on the means by which the alloying elements develop mechanical properties. In non-heat-treatable alloys the material strength depends on the effect of work hardening and solid solution hardening of alloy elements such as magnesium, and manganese, the alloying elements are mainly found in the 1xxx, 3xxx and 5xxx alloy aluminum series. In heat-treatable alloys, the material hardness and strength depend on alloy composition and heat treatment (solution heat treatment and quenching followed by either natural or artificial ageing). Principal alloying elements are defined in the 2xxx, 6xxx and 7xxx alloy aluminum series.
Alphanumeric temper designations are used after the alloy designation specifying how the alloy has been mechanically and/or thermally treated to achieve the properties desired. The following five aluminium alloy temper designations, denoted by capital letters (F, O, H, W, or T)) relate to the general class of treatment.
F, as fabricated. Most F-temper products are “semi-finished” products. They are used in shaping, finishing or thermal processes to achieve other finished forms or tempers.
O, annealed. Annealing treatments are used to achieve the lowest-strength condition for the alloys to maximize their workability or increase their toughness and ductility.
H, strain-hardened. This code is used for non-heat-treatable alloys that have had their strength increased by strain hardening, usually at room temperature.
W, solution heat-treated. This designation applies only to alloys that age naturally and spontaneously after solution heat treating.
T, thermally treated. This designator applies to any product form of any heat-treatable alloy that has been given a solution heat treatment followed by quenching and aging.

In selecting an aluminum alloy, its mechanical and other properties should be carefully considered. For an alloy such as 2024 aluminum, some important measures are ultimate strength, yield strength, shear strength, fatigue strength, as well as the modulus of elasticity and shear modulus. These values provide important information on the workability, strength, and potential uses of the alloy. The yield and ultimate strengths are the maximum amount of stress that will non-permanently and permanently deform a specimen of alloy, respectively. 2024 aluminum has impressively large ultimate and yield strengths at 469MPa (68,000 psi) and 324 MPa (47,000 psi), which makes it attractive for high-strength structural materials such as aluminum tubing.
Shear and fatigue strength are measures of a material’s resistance to specific stressors. For shear strength, this means the resistance to shearing stresses, also known as “cutting” stresses. The shear strength of 2024 aluminum is 283 MPa (41,000 psi), which is moderately strong while still allowing it to be cut from common bar stock. The fatigue strength is the measure of how resistant a material is to breaking under such fatigue. It is a valuable measure for alloys that appear in aerospace applications such as 2024 aluminum. Aircraft experience periodic stresses (such as from takeoff, landing, etc.), may not deform the alloy initially but, when repeatedly exposed, the alloy may weaken microscopically and then eventually macroscopically. The fatigue strength for 2024 aluminum is 138 MPa (20,000 psi), calculated with 500,000,000 cycles of loading under the yield point. Finally, the modulus of elasticity and shear modulus are parameters that display how “resilient” a given material is to deform. They give a good idea as to a material’s resistance to permanent deformation. For 2024 aluminum alloy, the modulus of elasticity is 73.1 GPa (10,600 ksi), and the shear modulus is 28 GPa (4,060 ksi), which is even greater than that of other high strength aircraft alloys such as 7075 aluminum.
