Market Key Figures & Performance Summary

Key Market Growth Drivers

1. Automotive Lightweighting and Electric Vehicle (EV) Transition

Automotive original equipment manufacturers (OEMs) are increasingly utilizing extruded and cast aluminum alloys to replace heavy steel components. From structural chassis frames and body-in-white (BIW) panels to battery enclosures in electric vehicles, high-strength aluminum alloys contribute directly to weight reduction, extended battery driving range, and improved fuel efficiency.

2. Rising Demand in Aerospace and Defense Structures

Aerospace operators demand high strength-to-weight ratios, corrosion resistance, and thermal durability. Specialty heat-treatable aluminum alloys (such as 2000 and 7000 series) remain primary structural materials for commercial aircraft wing spars, fuselage skins, and military defense hardware.

3. Sustainable Architecture and Green Building Certification

Aluminum's infinite recyclability without loss of structural properties aligns with global sustainability targets. The building and construction sector extensively utilizes extruded aluminum profiles for energy-efficient curtain walls, window frames, and structural roofing panels in green-certified building projects.
