Denso and Aisin are developing products with reduced reliance on rare earth materials to mitigate semiconductor-related supply chain risks. This strategic shift follows recent financial reports and aims to strengthen resilience against potential material shortages and geopolitical instability.
Context
Japanese automotive giants Denso and Aisin are accelerating the development of components with significantly reduced rare earth content to insulate their supply chains from geopolitical volatility and price spikes. As critical players in the global semiconductor and electric vehicle ecosystem, these companies aim to minimize dependency on imports, particularly from China, which currently dominates the rare earth market. By redesigning motors and power modules to function with little to no heavy rare earths, they are fortifying their production stability against the resource nationalism impacting the broader electronics sector.
Denso has already commercialized a motor that eliminates heavy rare earths like dysprosium, while Aisin is targeting a 50% reduction in neodymium usage for its next-generation eAxle systems. These technological pivots are expected to scale throughout 2025 and 2026, directly impacting long-term margin resilience. For investors, this shift represents a strategic de-risking of the energy transition, ensuring that production volume remains insulated from the supply shocks that have previously crippled the semiconductor and automotive industries.
