Market Driver

Growing Focus on Lightweight Materials in the Automotive Sector

Automotive manufacturers are under pressure to improve fuel efficiency and reduce emissions. This shift is driving interest in lightweight and high-strength materials. The U.S. Department of Energy, states that lightweight materials hold strong potential to improve vehicle efficiency. Reducing a vehicle’s weight by 10% can lead to a 6 to 8% improvement in fuel economy.

Replacing conventional cast iron and steel with materials like high-strength steel, aluminum alloys, magnesium alloys, carbon fiber, and polymer composites can cut the weight of a vehicle’s body and chassis by up to 50%, significantly lowering fuel consumption. Integrating such materials into just 25% of the U.S. vehicle fleet could save over 5 billion gallons of fuel annually by 2030.

HEAs offer a promising alternative to conventional steels and alloys due to their exceptional mechanical properties. Their use in electric vehicle components, structural frames, and crash-resistant parts is gaining momentum, making the automotive sector a key contributor to the growth of the high-entropy alloys market globally.
