Most Common Uses of Aluminum
But thanks to the ongoing evolution of production processes, new blends are speeding along a cost-effective mass-market shift from steel to aluminium, which is especially noticeable in the automotive industry.
To reach and improve upon those goals, OEMs have started researching new aluminium alloys that can enable even higher strength and ductility than older aluminium series. But not all news articles extolling the virtues of new aluminium alloys and their production techniques should be seen as reliable: some releases are just adverts for certain companies or are merely promoting half-baked ideas that may not even come to fruition.
The truth is that all leading aluminium producers and processors have, alongside the usual mixes, their own proprietary alloys, used especially in aluminium-intensive industries such as packaging, automotive, aerospace and constructions.
In a field crowded by so many different alloys, separating the products with real added value from publicity stunts is therefore no easy task. This overview is intended to serve as a backgrounder on some of the main aluminium alloys used in the automotive industry and flag the latest research trends. Alloys for use in the automotive industry are classified in several categories: cast, extruded and rolled alloys, each meant for different parts and positions in vehicles.
Depending on their chemical composition and properties, automotive alloys are designated by series mostly 6xxxx and 5xxxx. Each series contains numerous variations and subgroups, depending on composition, manufacturing techniques and the tempers exp. T4, T6 of various alloys. The transition is promoted by OEMs demanding higher strengths, which are more readily achieved using the AA6xxx alloys.
While 5xxx series alloys have excellent strength-to-weight ratio, formability properties and full recycling compatibility, 6xxx series have the upper hand as they are versatile, heat-treatable, highly formable and well weldable. Aluminium alloy AAA , with excess silicon content originally launched by Alusuisse at the turn of millennium is mainly used in Europe for external panels in vehicles.
The AA alloy is used in aluminium intensive models developed by Jaguar and Land Rover, with copper as an alloying metal copper level of 0. Other than their innate chemical properties, there are various techniques that give finished alloys their final characteristics, such as: bake hardening, work and precipitation hardening, heating, annealing etc.
Those processes can provide endow an alloy with specific properties like higher strength, formability or hemming quality. AAA is a less strong but more formable alloy that has a lower bake hardening response than AA It is the same alloy Novelis promotes for external panels under the name Advanz e Advanz e is a heat treatable, balanced alloy specifically designed and optimized for high-strength requirements, both for skin and structural applications.
It has excellent strength in T6 condition, achieving strengths of around MPa, making it ideal for structural applications in chassis and cross member components.
AAA was added more recently thanks to recycling aspects. This alloy is mostly used for outer panels in gauges of 0. AA , used in car steering knuckles for instance, has an average tensile strength of MPa and elongation The alloy was optimised by adding minor quantities of zirconium, zinc and copper. Another well-established alloy with high magnesium content, AlMg5Mn AA , is used for high strength and complex stampings, for inner panels, offering corrosion resistance and high formability, while its sister alloy AA offers superior surface quality and is used in structural sheet applications.
The common thread linking these developments together is that the number of aluminium alloys produced from recycled aluminium is increasing, a trend that is expected to continue well into the future. It contains a record low percentage of scandium 0. This alloy uses copper rather than silicon as the strengthening component.
ACMZ needs further testing and development before it appears in the makeup of an engine. The super lightweight, heat-treated AA alloy of Enduralum helps reduce overall weight while maintaining a reliable clamp load. Another proprietary blend from Arconic is the C6A1 alloy, used by FCA, which allows automakers to create high-form lightweight design solutions in applications that require strength and durability.
Norsk Hydro recently introduced three new aluminium alloys , and alloys in order to improve the superplastic forming process by reducing the process time and rendering them more attractive to the automotive industry. These alloys are specifically meant for the hot-metal forming of aluminium sheet, for complex automotive components. Most of the major suppliers are now developing AA7xxx automotive sheet alloys in an attempt to meet the higher expectations OEMs have for greater strength.
However, the AA7xxx alloys with additions of Zn , aside of higher cost, have to overcome both corrosion and stress corrosion issues, particularly for alloys that are conventionally weldable. Consequently, the AA6xxx alloys remain the predominant materials used in automotive applications for now. Welding of aluminium alloys with each other, or with other metals, is also an issue that needs further technology improvements and innovations.
Recent discoveries have lead to the conclusion that this problem will soon be overcome, which would consequently accelerate their adoption by auto manufacturers. Factors such as tool geometry, choice of welding parameters, post-weld heat treatment PWHT , workpiece thickness, thermal cycle during welding, and auxiliary cooling greatly influence the resultant microstructure and strength of the weldment.
Compared with conventional 3xxx casting alloys, this one eliminates brittle silicon particles, allowing for better properties. The result is significantly higher tensile and fatigue strengths MPa T. EverCast achieves excellent fluidity and resistance to hot cracking and shrinkage formation. Recent research also showed that overaged copper containing 7xxx-series alloys provide robust crack and corrosion resistance in tests. The 3 rd generation of Al—Li alloys aluminium-lithium could also become integral to various components of luxury cars thanks to their excellent combination of low density, high strength, high stiffness, and excellent damage tolerance.
In the past, these alloys were reserved for use in the aerospace industry. Over the past ten years, Airware alloy joined as a preferred plate material for both pressurized and non-pressurized structural components used in space launchers and crew modules requiring a thickness range of 1.
Aluminium alloyed with scandium creates an extra strong, lightweight alloy with excellent resistance to corrosion and has good weldability. These alloy properties can be achieved with scandium additions in the range of 0. Thanks to its fine grain refinement, Al-Sc alloys reduce hot cracking in welds, increase strength and delivers better fatigue behaviour.
While these alloys are rather expensive several times more than aluminium , and more focused for applications in the aerospace industry, further developments and decreasing scandium costs will increase their use in the automotive industry. Recent investments in scandium mining especially in Australia will hopefully lead to price levels that are acceptable for automakers.
If conventional alloys tend to be cheaper and are increasingly relying on recycled scrap to achieve lower costs, the crop of cutting edge alloys is substantially more expensive, making them too pricey for most automakers. However, their price point is expected to decline in the future due to things like higher commercial use and higher availability of alloyed metals.
Once that happens, automotive producers will be much more likely to adopt them. Discovering and commercially adopting new aluminium alloys is a long and arduous process. In recent years, this has been helped along by more powerful computer software that can calculate the effects of alloying elements and predict the behaviour of a certain alloy, based on its chemical composition and alloy improvement procedures after production.
New, superior and improved aluminium alloys have become — and are likely to stay — the main lightweighting materials in vehicles. The only obstacle remains their relatively high price compared to steel, but still affordable compared to carbon fibre reinforced plastics CFRPs. The deciding trend that will dominate aluminium alloys characteristics in the future for automotive OEMs is superplastic forming.
The process enables aluminium manufacturers to produce thin-walled aluminium sheet components. Another trend, though not correlated to the first one, is the increasing presence of recycled scrap content in future aluminium alloys used by auto industry. The takeaway from these two trends for smaller primary aluminium producers around the world that are barely surviving in the current low price market environment or are coping with losses is simple.

Aluminium Alloys in the Automotive Industry: a Handy Guide
Aluminum Al , also spelled aluminium , chemical element , a lightweight, silvery-white metal of main Group 13 IIIa, or boron group of the periodic table. Because of its chemical activity, aluminum never occurs in the metallic form in nature, but its compounds are present to a greater or lesser extent in almost all rocks , vegetation, and animals. Aluminum occurs in igneous rocks chiefly as aluminosilicates in feldspars , feldspathoids , and micas ; in the soil derived from them as clay; and upon further weathering as bauxite and iron-rich laterite. Bauxite, a mixture of hydrated aluminum oxides, is the principal aluminum ore.
But thanks to the ongoing evolution of production processes, new blends are speeding along a cost-effective mass-market shift from steel to aluminium, which is especially noticeable in the automotive industry. To reach and improve upon those goals, OEMs have started researching new aluminium alloys that can enable even higher strength and ductility than older aluminium series.

Fabrication refers to any process that cuts, shapes, or otherwise forms a material into an end product, and this article covers the advantages and disadvantages of plastic over metal fabrication, and vice versa. The type of fabrication method used to produce a particular item depends on a wide range of factors, including the products purpose, appearance, and available budget. Before determining whether plastic or metal fabrication is appropriate for a particular job, it is important to first understand the potential advantages and disadvantages of each option.
Aluminium was one of the newest metals to be discovered by humans. Aluminium does not occur naturally in its purest form so it was not discovered until the 19th century with developments in chemistry and the advent of electricity. Aluminium has gone on an incredibly interesting journey from a precious metal to the material used virtually in every sphere of human life in just one and a half centuries.
The History of Aluminium Industry
The start was a modest one, however. Because of the complexities of refining aluminum from ore, aluminum was considered more rare and precious than gold or silver through most of the 19th century. A pure form of the metal was first successfully extracted from ore in by Danish chemist Hans-Christian.
