Magnesium Alloys Market

The global magnesium alloys market is gaining steady momentum as manufacturers in automotive, aerospace, electronics, and biomedical sectors push aggressively for lightweight, high-performing materials. Magnesium alloys are among the lightest structural metals used at scale, offering high specific strength, good castability, vibration damping, and excellent machinability. These characteristics translate into tangible benefits such as improved fuel economy and EV range, faster cycle times in die casting, and weight reductions across mobility platforms. According to Global Infi Research, this analysis outlines the market’s structure, technology frontier, regional dynamics, and strategy playbook to navigate growth while managing risk.

Across most reputable industry assessments, the market is growing at a mid–single to low–double digit pace, with the long-run trajectory tied to the penetration of EVs, the intensity of lightweighting in ICE platforms, the revival of civil aviation production, and the re-shoring of supply chains. The market’s core is still die-cast magnesium (notably AZ- and AM-series alloys like AZ91D, AM60, AM50), which dominates powertrains, body-in-white components, steering wheels, seat frames, brackets, housings, and 3C electronics casings. Wrought magnesium (extrusions, rolled products, forgings) remains a smaller yet strategic segment for aerospace, defense, and emerging biomedical applications. While cost, corrosion, and ignition resistance have historically constrained magnesium’s share versus aluminum and composites, recent R&D is closing these gaps and expanding the feasible design window.

From an ESG perspective, magnesium’s lightweight advantage contributes to lower use-phase emissions in transport. Additionally, advances in recycling and secondary magnesium flows are improving circularity. However, stakeholders must also address supply concentration risks, energy intensity in primary production, and responsible sourcing to meet corporate sustainability targets.
