Raw-Material And Energy-Cost Volatility In Pidgeon And Electrolytic Routes

In 2024-2025, the Pidgeon process, which requires coal and ferrosilicon to produce magnesium, faced squeezed producer margins due to coal prices fluctuating. For electrolytic output, which demands significant energy per ton, feasibility efforts in Norway hit a snag when power quotes surged, surpassing the breakeven point. By late 2025, cash costs increased, driven by dolomite feedstock inflation and power rationing in Inner Mongolia. The lack of hedging instruments exposes market participants to spot volatility, hindering long-cycle investments and complicating off-take negotiations.

Corrosion/Flammability Concerns Limiting OEM Specifications

Magnesium's electrochemical potential of -2.37 V makes it susceptible to galvanic corrosion, especially when placed alongside steel or aluminum^{[1]Society of Automotive Engineers, “SAE ARP6256—Aircraft Seat Applications,” sae.org} . As a result, OEMs are compelled to apply insulating gaskets and coatings, which inflate system costs. Field audits on seat frames for the 2024 model year, after exposure to salt during winter, uncovered localized pitting. This discovery has led some automakers to reconsider aluminum alternatives, sacrificing weight savings in the process. The flammability of magnesium during machining necessitates increased capital for specialized ventilation and fire-suppression systems. Furthermore, European automakers now mandate proof of ISO 16220 compliance, extending supplier-qualification cycles. Consequently, this cost-risk assessment has hindered deeper penetration into the mass-market vehicle segments.
