How is Aluminium Made from Scrap?

More producers over other metals prefer aluminium. While some industries, like construction, depend on aluminium’s durability, others rely on its adaptability and convenience. Natural oxides produced by aluminium provide a thin barrier against corrosion. Additionally, due to its distinct properties, aluminium may be recycled repeatedly. Even after several reuses and cycles of recycling and years of storage, it keeps its physical and chemical characteristics. It means that recycled aluminium used in manufacturing processes is just as sturdy, flexible, and stable today as it was when it was first inserted into a consumer good decades ago. Additionally, because it is entirely recyclable, there will be no waste or material loss over time. 

The abundance of secondary and scrap aluminium in affluent nations supports a sizable recycling industry. Aluminium production from raw materials often has an energy cost of over 90% more expensive than recycling aluminium. Additionally, almost 75 percent of the aluminium created throughout history is still used today. It has recycled thousands of aluminium items, cutting waste and assisting in the reduction of pollution. The aluminium price per kg is 2.36 AUD.

Recycling Process 

For numerous reasons, notably printability, aluminium are the material of choice for beverage manufacturers and food packaging businesses. At the end of its useful life, more than 90% of aluminium used in building components and automobile parts is recycled. However, rates for aluminium used in consumer packaging are lower.

Secondary and scrap aluminium is shredded and sorted to eliminate glass, metal, and other contaminants. Over 1200°F is used to liquefy recycled scrap metal, which is poured into molds and shaped into aluminium ingots. The same oxides that cause corrosion resistance start to show up after coming into touch with the environment. Using a skimming tool, these oxides are eliminated. Dross is processed to remove any useful components.

  1. Collecting Scrap

New scrap is extra aluminium material produced as an offshoot of the manufacturing and fabrication processes, while old scrap is aluminium used by consumers and discarded. Smelters can collect aluminium from other community areas.

  1. Sorting Scrap

Aluminium smelters group all uncoated aluminium and all coated aluminium together, and Non-aluminium materials are removed in this stage.

  1. Crushing

In the third step, sorted aluminium scrap is compacted and crushed into bales. 

  1. Remelting

Removes any coating on the aluminium scrap before it’s transferred to the smelter or large furnace.

Uncoated aluminium scrap is directly loaded into a smelter, which converts into molten form after being heated at high temperatures. 

  1. Casting

In the last step of the aluminium recycling process, molten aluminium is cast at high temperatures to form ingots or pieces of aluminium cast into suitable shapes for processing. 

Ingots are then transferred to aluminium manufacturing or processing plants to produce new products.


Work with professionals to buy or sell environmentally friendly scrap and secondary aluminium or copper for industrial processes. They are the only market intelligence specializing in aluminium and copper scrap price and forecasts. They don’t work with other metals, meaning they can focus all their energy and resources on providing the best aluminium data possible.
