Aluminum alloy metal is forced through a die with a specified cross-sectional profile during the aluminum extrusion process. Profiles can be heat treated after extrusion is finished to improve their characteristics. By forcing heated alloy material through a die, aluminum extrusion is a procedure for producing objects with precise cross-sectional profiles. The shapes can be basic or complex, solid, hollow, or semi-hollow. The aluminum extrusion industry aids the architectural, automotive, electronics, aerospace, energy, and others in various ways.
In the transportation and construction industries, aluminum extrusion has largely replaced steel due to its lightweight, corrosion-resistant, and infinitely recyclable qualities. The largest market for aluminum extrusion is in the building and construction industry. Annual recycling of the aluminum used in construction is thought to be around 65%. In the near future, it is anticipated that its use in doors, windows, panels, window frames, ladders, and bridges will rise.
Extruding aluminum can improve both the material's corrosion resistance and attractiveness. However, there are further advantages. For instance, the anodization process thickens the metal's naturally occurring oxide layer, increasing the metal's resistance to corrosion and wear while simultaneously increasing surface emissivity and creating a porous surface that can receive various colored dyes.
There are numerous steps in the extrusion process. The first step is to prepare and transfer the extrusion die to the extrusion press. After that, a billet of aluminum is heated up before being extruded. Thereafter, extrusions are guided along the runout table and quenched, and then extrusions are sheared to table length, cooled to room temperature, moved to the stretcher, and stretched into alignment. Extrusions are then transferred to the finish saw and lengthened. Profiles can be heat treated to improve their qualities once extrusion is finished. Then, after heat treatment, they can receive various surface finishes to enhance their appearance and corrosion protection. In order to get them to their ultimate dimensions, they can also go through fabrication processes. Various finishing processes can be applied to aluminum profiles.
The market size of the aluminum extrusion industry is estimated at USD 87.84 billion in 2021 and is anticipated to rise at a 7.5% compound annual growth rate (CAGR) from 2022 to 2030. Aluminum content is rising in internal combustion and electric vehicles (EVs), which is expected to spur market expansion throughout the projection period. The legal obligations regarding the environmental impact of vehicles are putting growing pressure on automakers to comply.
Due to its remarkable malleability, aluminum can be easily extruded into various shapes. In the automotive and transportation industry, aluminum forms are used in trucks, vehicles, boats, railroad engine blocks, transmission housings, roof rails, panels, and chassis. In order to make automobiles lighter, structural components are becoming more and more in demand. The majority of market participants are concentrating on the creation of lightweight materials for downstream industries. The players' main objective is to win new business from various end-use sectors. Because consumer goods have fewer aluminum applications than other sub-segments, they will hold the smallest market share in 2021. However, rising consumer goods production is anticipated to propel the aluminum extrusion industry.
In 2021, Asia-Pacific held the greatest revenue share of more than 69% and dominated the world market. Large aluminum extrusion companies in the region will keep it in the lead throughout the anticipated years.
