The automotive industry is a significant driver of the magnesium alloy market due to stringent emission regulations and the global trend toward lightweight vehicles. Magnesium alloys offer a superior strength-to-weight ratio, making them suitable for engine blocks, transmission cases, and EV structural components. Automakers use these alloys to improve fuel efficiency and enhance performance. In 2025, SAIC Motor introduced a mass-produced magnesium alloy case for electric drive systems, utilizing a semi-solid AZ91D alloy, which weighs just 13.7 kg. Tesla and Audi also integrate magnesium components for energy efficiency.
Magnesium alloys are witnessing increased adoption across aerospace, defense, and consumer electronics sectors owing to their lightweight nature, structural strength, and energy efficiency benefits. In aerospace and defense, these alloys are used in aircraft fuselage components, landing gear systems, satellite parts, and reusable space vehicles to reduce fuel consumption, improve payload capacity, and lower launch costs.
Companies such as Airbus and Luxfer MEL Technologies have started utilizing specialized alloys such as Elektron® 43 and 21 in commercial and space-grade applications. Major OEMs such as Apple and Lenovo have incorporated magnesium alloy frames into their products, leveraging recyclability and design flexibility.
The high cost of raw materials and price volatility act as major market restraints. Magnesium production is energy-intensive and depends on limited sources such as dolomite and brine. With China being the largest supplier, environmental regulations and output restrictions often cause global price spikes. For instance, in 2022, China's production curbs led to a sharp increase in magnesium prices, disrupting supply chains and raising input costs worldwide.
Another restraint is the inherent corrosion susceptibility and poor weldability of magnesium alloys. They corrode rapidly in moist or saline environments, requiring expensive protective coatings, which increases processing costs. Automakers such as BMW apply anti-corrosion coatings on magnesium engine parts, but these processes add to production complexity and time. Although new coating technologies and hybrid welding methods are under development, they are not yet cost-effective for large-scale use.
Magnesium alloys also suffer from limited formability at room temperature due to their hexagonal close-packed (HCP) crystal structure. This necessitates advanced processes such as thixomolding, increasing tooling costs. For example, Ford employed hot-forming techniques for magnesium parts in the F-150, but the high cost and complexity limited broader deployment. Such limitations restrict magnesium alloy adoption in regions including Japan, known for precision manufacturing.
As automakers increasingly prioritize vehicle light weighting for improved fuel economy and electrification, magnesium alloys, which are 32% lighter than aluminum, are becoming the material of choice for critical components such as wheels, seat frames, transmission cases, and engine cradles. For example, GM uses AE44 magnesium alloy in the Chevrolet Z06 Corvette for weight reduction and performance enhancement.
The rapid expansion in the EV market, which is projected to grow at a 14.6% CAGR between 2025 and 2032, also strengthens the magnesium alloy market. Drivers include advancements in battery technology, economies of scale in EV manufacturing, and declining vehicle costs that make EVs more accessible. Meanwhile, zero-emission mandates, tighter emission regulations, and generous government incentives are accelerating EV adoption, particularly in Europe, China, and North America, where charging infrastructure and policy frameworks are rapidly advancing.
Magnesium alloy suppliers align their offerings with EV-specific needs such as lightweight battery casings, motor housings, and chassis components. Strategic collaborations, such as CATL’s 2019 magnesium material joint venture, highlight the importance of integrating into the evolving EV supply chain.
Magnesium alloy manufacturers can also tap into high-growth verticals such as biomedical devices and advanced manufacturing technologies. Magnesium’s biocompatibility and biodegradability make it ideal for orthopedic implants, cardiovascular stents, and surgical screws, which naturally dissolve in the body, reducing the need for follow-up surgeries. The FDA’s Breakthrough Device designation for Magnesium Development Company’s bioresorbable HC orthopedic screw validates its clinical potential and paves the way for faster regulatory review and broader adoption in orthopedic care.
Based on alloy type, the cast alloys segment is anticipated to dominate, accounting for a market share of approximately 63% in 2025, due to its widespread use in automotive, aerospace, and electronics applications, where lightweight and durable components are critical for energy efficiency and performance Cast alloys are produced by pouring molten magnesium into a mold, allowing it to solidify into the desired shape. These alloys typically contain aluminum, manganese, and zinc, each contributing to strength, corrosion resistance, and durability. Advanced compositions including zirconium and rare-earth metals have recently incorporated to enhance creep resistance, especially in high-temperature applications. Heat treatments further improve the mechanical properties of cast magnesium alloys, making them suitable for complex geometries in engine blocks, housings, and structural components.
The wrought magnesium alloys undergo mechanical deformation processes such as forging, extrusion, and rolling to achieve the required shapes and mechanical characteristics. These alloys use aluminum, manganese, and zinc as base alloying elements and are classified into heat-treatable and non-heat-treatable variants. Wrought alloys offer superior ductility and a clean-surface finish compared to cast alloys, making them ideal for structural applications in aerospace and transportation sectors where formability and strength-to-weight ratio are key performance factors.
By application, the automotive & transportation segment is expected to remain the dominant end-use sector, accounting for over 54% of the total market share by 2025. This is driven by the growing emphasis on lightweight materials that enhance fuel efficiency and support emission reduction goals, particularly in electric and hybrid vehicles.
Magnesium alloys are increasingly adopted across industries due to their advantageous properties, including low density (1.8 g/cm³), high strength-to-weight ratio, excellent castability, thermal conductivity, and recyclability. These attributes make them highly suitable for lightweight structural automotive parts such as engine cradles, transmission housings, seats, steering columns, and dashboard components. Despite the production costs, process limitations, and stringent regulatory standards, the push toward sustainable mobility will accelerate its market penetration.
In the aerospace and defense sector, alloys such as WE43, RZ5, MSR, and EQ21 are gaining traction for use in rotor gearboxes, compressor casings, and auxiliary systems, with WE43 increasingly replacing legacy alloys in platforms such as the Sikorsky S92 and Eurocopter EC120. In motorsports, advanced alloys such as WE54 are used in high-performance applications, including Formula-one engine components and forged pistons, due to their superior strength and thermal resistance.
The Asia Pacific region will continue to lead the market, holding over 45% of the total market share in 2025. This leadership stems from rapid urbanization, the region’s strong manufacturing base, and expanding end-use industries such as automotive, aerospace, and consumer electronics.
