Aluminum is used in the automotive industry to produce a variety of parts. The distribution of aluminum in a typical car, and the percentage of those parts that are cast or wrought aluminum alloys,. For recycling purposes, the distinction between cast and wrought aluminum is very important since only pure wrought aluminum scrap can be recycled into a wrought aluminum product again. Currently, the only technique available to reduce the levels of alloying elements when recycling wrought aluminum is dilution. A mixture of cast and wrought scrap can only be recycled into a cast aluminum product. It is clear from Table 2 that the majority of aluminum in the automobile is cast, but this percentage is expected to change dramatically when aluminum car panels, which are mostly wrought alloys, capture a larger percentage of the automotive market by replacing steel which is currently used for these applications. In order for this to occur, the recycle ability of wrought alloys needs to increase substantially to meet the increasingly stringent government regulations.

Aluminium production is a time-consuming and energy-intensive process. But once the aluminium is made, it can be recycled over and over without losing its superb qualities.

The production process includes many phases. Here is an overall view on the various steps, showing aluminium production way from mine to recycling.This need is being met by advances in the technology for sorting aluminum scrap not only into cast and wrought aluminum alloys, but also into their individual alloy groups. The purpose of this report is to review established and developing technologies for sorting aluminum scrap from end-of-life vehicles.

Aluminium is everywhere, and the applications for this element are many. You may not always be conscious about aluminum presence, but you would definitely miss it.

Huge Resources

  • Most abundant element in the earth’s crust, after oxygen and silicon
  • Today, bauxite is the only commercial ore used for production of aluminium. In the future, we might have more sources for aluminium
  • With today’s aluminium production, the bauxite reserves will last more than 100 years

Strong & Light

  • 2.7 (g/cm3) = 1/3 the weight of steel
  • Low weight means reduced energy consumption in transportation
  • Low weight is an advantage during assembly in buildings and in many other applications.

Perfect for food packaging

  • Aluminium foil is completely impermeable – no taste, aroma or light gets in or out
  • Widely used in food and drink packaging
  • Efficient conservation of food reduces wastage
  • Low weight reduces packaging in transportation
  • Impermeability also reduces cooling needs


  • Aluminium in buildings, construction and transport is fire-proof
  • Will only burn if shaped as very thin film
  • Will melt at 660° C without releasing any gases

Easy to form

  • Aluminium is ductile and has a low melting point
  • Easy to process in cold and hot condition
  • This allows design flexibility and integration in advanced transport and building industries

Superconductor for heat and electricity

  • Twice as good a conductor as copper
  • This makes aluminium the best choice for energy-efficient systems for electrical transmission, such as transfer components

Great reflector

  • Can reflect both heat and light
  • Combined with its light weight, this makes aluminium ideal for reflectors like light fittings
  • High energy efficiency in the reflectors reduces energy consumption

  Long life – low maintenance

  • Aluminium forms a protective oxide coating that makes it highly corrosion resistant
  • This prolongs the life of aluminium in cars and buildings
  • Reduces need for maintenance
  • Reduces environmental impacts due to replacements and maintenance
