They demand high consistency, metallurgical precision, and certified quality, often requiring suppliers to meet global logistical and volume requirements. Specific end-user applications include manufacturers of electric vehicle battery enclosures, specialized casting houses producing engine blocks for high-performance ICE vehicles, and forging companies specializing in lightweight wheel production.
The fastest-growing segment of potential customers includes emerging EV startups and dedicated electric vehicle manufacturing divisions of established OEMs. These entities prioritize performance and range, leading to higher per-vehicle aluminum content compared to traditional ICE platforms. Additionally, the heavy-duty commercial vehicle segment, while smaller in volume, is increasingly adopting aluminum alloys for structural components to maximize payload capacity and improve fuel efficiency, representing a growing niche customer base for high-strength aluminum extrusions and castings.
