Aluminum Radiators Dominate Market as Auto Brands Prioritize Lightweighting

Release Time：2025-04-08

The global automotive radiator market is undergoing a significant shift toward aluminum materials, driven by stringent fuel efficiency regulations and the rise of electrification. Aluminum radiators now command a 65% market share, according to a recent report by MarketsandMarkets, with demand projected to grow at a 7.2% CAGR through 2030.
"Aluminum offers a 30% weight reduction compared to copper while maintaining comparable thermal performance," explained Houjixing, CEO of Dexin Radiator. The material’s corrosion resistance is further enhanced through advanced coatings, extending product lifespan to over 10 years. Key innovations include graphene-reinforced alloys and 3D-printed fins, which increase heat dissipation by 25%.
Despite higher upfront costs, aluminum radiators reduce long-term maintenance expenses by 40%, making them a preferred choice for automakers like Tesla and BYD. Industry analysts predict copper radiators will be phased out of passenger vehicles by 2035.
