As Electric Vehicles Go Mainstream, Automakers Turn to Aluminum Extrusions — and Chinese Manufacturers Race to Meet Demand
The global shift towards new energy vehicles (NEVs) is fundamentally changing vehicle design, with aluminum emerging as a pivotal material. As automakers strive to enhance driving range, reduce vehicle weight, and accommodate heavier battery packs, aluminum is increasingly replacing steel in both structural and functional components. Analysts anticipate this trend will intensify throughout the decade.
Electric vehicles (EVs) typically weigh several hundred kilograms more than their gasoline counterparts due to battery mass. To mitigate this added weight without compromising performance, manufacturers are increasingly deploying lightweight aluminum extrusions for components such as battery enclosures, chassis members, crash-management structures, and exterior accessories. Aluminum’s favorable strength-to-weight ratio, resistance to corrosion, and recyclability position it as a key material in the burgeoning aluminum sector, with rapid demand growth seen in electrifying markets like China, Europe, and North America.
This escalating demand is pushing aluminum extrusion suppliers to not only demonstrate capacity but also ensure consistent quality. A single batch of inferior billet can jeopardize the structural integrity of critical components. As a result, automakers are reportedly narrowing their supplier options to those who can guarantee quality control throughout the entire production process.
Syntech Metals Limited: Pioneering Control in Aluminum Production
Syntech Metals Limited, a vertically integrated aluminum extrusion manufacturer based in China, has established its automotive business on stringent quality control. Unlike smaller extrusion houses that often source their billet from third parties, Syntech operates its own melting and casting facilities, allowing it to procure high-grade aluminum ingots and cast billet in-house.
“In an industry where external sourcing can introduce quality inconsistencies, we take pride in our in-house processes,” says Ken Yip, Sales Director at Syntech Metals. “We control everything from raw ingot to extrusion, ensuring our automotive clients get consistent alloy and temper specifications.”
Syntech produces aluminum billet in various tempers, specifically AL6063-T5, T6, and AL6061-T6, which align with the distinct hardness and machinability requirements of automotive components. This meticulous casting process, coupled with ISO 9001:2015 and IATF 16949 certifications, minimizes issues related to inconsistent chemistry and impurities often found in externally sourced billeted aluminum.
Comprehensive Product Range for the Automotive Sector
Syntech’s automotive product line includes aluminum bumpers, crash-management bars, and accessories like aluminum roof rack cross bars, among other extrusions for electric vehicles. The company utilizes both 6000-series and 7000-series alloys to achieve the optimal balance of strength, weight, and corrosion resistance for applications ranging from EV battery enclosures to chassis components, facilitated by in-house CNC machining.
Founded in 1993, Syntech operates a vast 100,000-square-meter facility equipped with 17 extrusion presses, producing a range of components and shipping over three million aluminum parts to clients in more than 70 countries, including North America, Europe, Australia, and South Africa. With a growing focus on automotive and EV supply relationships, the company is capitalizing on the escalating demand for vehicle parts in markets experiencing rapid EV adoption.
Aluminum Demand Beyond Electric Vehicles
The move toward aluminum in vehicle manufacturing is not confined to electric models. Hybrid and plug-in hybrid vehicles also contend with increased weight from their dual powertrains. Furthermore, traditional combustion vehicles are integrating aluminum extrusions to meet tightening fuel efficiency and emissions standards. This diverse demand base is expected to maintain automotive extrusions as one of the aluminum sector’s fastest-growing product categories.
As automotive companies assess extrusion suppliers, the emphasis is gradually shifting from merely price to traceability and process control. “Automakers and Tier 1 suppliers are increasingly scrutinizing the source of aluminum,” Ken adds. “The ability to state ‘we cast it ourselves’ offers a crucial competitive edge.”
As the production of new energy vehicles expands globally, suppliers equipped with in-house billet casting, automotive-grade certifications, and machining capabilities are well-positioned to capture an increasing share of a market projected to be one of the aluminum industry’s strongest growth areas in the coming years.
