Scrap aluminum extrusion refers to discarded or surplus aluminum profiles or shapes that have been manufactured through the extrusion process. Extrusion is a manufacturing technique where a metal billet, in this case, aluminum, is forced through a die to create a specific cross-sectional shape. This process allows for the production of various profiles such as beams, angles, channels, tubes, or custom shapes.

Scrap aluminum extrusion occurs when these profiles or shapes are no longer needed or have been damaged during production or usage. This scrap can come from industrial processes, construction sites, or even consumer products.

Aluminum extrusion scrap is typically made up of aluminum alloys, which are mixtures of aluminum with other elements to enhance the material’s properties. These alloys often have desirable characteristics such as strength, corrosion resistance, and lightweight, making them valuable in various industries.

Recycling scrap aluminum extrusion is common due to the metal’s high recyclability. It can be melted down and reused to produce new aluminum extrusion profiles or other aluminum products, reducing the need for primary aluminum production and saving energy and resources in the process.
