MARKET DYNAMICS

MARKET DRIVERS

Rising Vehicle Electrification & Need for Weight Reduction Accelerate Lightweight Material Adoption

Automakers are under mounting pressure to increase EV range, hit stricter CO₂ and fuel-economy targets, and still offer larger, safer vehicles. Lightweight materials such as AHSS, aluminum, and advanced polymers are some of the few levers that improve efficiency without compromising safety. Hence, OEMs are systematically redesigning body-in-white, chassis, and battery structures around them, which is favoring automotive lightweight materials market growth. Recent life-cycle studies also show that using advanced steels for lightweighting can deliver large, long-term greenhouse-gas savings compared with not lightweighting at all, further strengthening the regulatory and sustainability case.

• For instance, a 2025 fact sheet from the American Iron and Steel Institute reports that lightweighting a studied vehicle fleet with advanced high-strength steel (AHSS) can avoid about 260 million tonnes of CO₂-equivalent emissions by 2053 and as much as 400 million tonnes when compared directly with an aluminum-based lightweighting scenario. This highlights how strongly climate targets are pushing OEMs toward lighter, more efficient structures.

MARKET RESTRAINTS

Difficulty Recycling Mixed-Material Vehicles to Limit Large-Scale Adoption

Next-generation cars mix steel, aluminum, polymers, composites, and electronic systems in tightly integrated structures, which makes end-of-life dismantling and high-quality material recovery far more complex than for older, mostly-steel vehicles. Shredding and bulk separation struggle with bonded composites, coated plastics, and mixed aluminum alloys. Furthermore, upcoming regulations in key markets are starting to demand higher recycled content and better design for disassembly. This raises questions about the circularity and residual value of very aggressive multi-material designs and acts as a brake on how fast OEMs can scale them.

MARKET OPPORTUNITIES

Growing Use of Multi-Material Architectures in Next-Gen Platforms Creates High-Value Material Mix Opportunities

New platforms are increasingly engineered around “the right material in the right place,” combining AHSS, aluminum, magnesium, composites, and engineered plastics exactly where they add the most performance per kilogram. This multi-material approach lets OEMs tailor stiffness, crash performance, NVH and thermal behavior while meeting stricter CO₂ limits and EV packaging needs, opening opportunities for suppliers who can co-develop grades, joining concepts and low-carbon variants for specific zones of the vehicle. Partnerships between OEMs and material producers around low-carbon aluminum and advanced steels show how high-value material innovation is becoming a core part of future platform roadmaps.

• For instance, in 2025, Mercedes-Benz announced that its new electric CLA uses low-carbon aluminum from Norsk Hydro, cutting the model’s production-phase CO₂ footprint by around 40% compared with its non-electric predecessor. The metal is produced using hydropower and contains a significant share of recycled scrap, illustrating how OEMs are combining advanced lightweight materials with cleaner production routes in next-generation architectures.
