全球鎂合金錠市場預計將從 2025 年的 221602 億美元成長到 2031 年的 288749 億美元,複合年成長率為 4.51%。
這些固體金屬鑄件,主要由鋁、鋅、錳等元素的合金構成,以改善其機械性能,在汽車和航太領域需求量極大。這種需求主要源於這些行業對輕量化的需求,旨在提高燃油效率並延長電動車的續航里程。 2024年,中國原生鎂產量達102.58萬噸,年增24%。這顯示中國擁有龐大的產能,足以支撐下游產業的發展。儘管如此,市場仍面臨諸多挑戰,尤其是在供應鏈集中化及其導致的價格波動方面。原生鎂生產高度依賴少數地區,使其極易受到地緣政治變化和監管政策調整的影響,可能阻礙國際製造商獲得穩定的供應。此外,主要生產國不斷上漲的能源成本和日益嚴格的環境法規可能導致生產成本上升,進而阻礙這些合金在對成本敏感的商業應用中的廣泛應用。

鎂合金錠市場的主要驅動力是電動車(EV)市場的快速擴張,這需要最佳化續航里程。隨著汽車製造商不斷推進車輛電氣化,電池組的重量成為一大負擔,因此必須大幅減輕結構部件的重量,以最大限度地提高續航里程和性能。鎂合金是結構金屬中強度重量比最高的材料,擴大被用於電池機殼、馬達外殼和橫樑等關鍵電動車零件,直接推動了鎂錠的消耗。這一趨勢也得到了中國鎂錠出口量的支撐。 2024年1月至11月,中國鎂錠出口量較去年同期成長24.78%,達到24.22萬噸,全球汽車製造商積極確保鎂錠供應,以達到輕量化目標。同時,合金技術的進步提高了鎂錠的耐腐蝕性和鑄造性能,從而拓展了其應用範圍。半固態射出成型成型技術的創新和新型合金牌號的開發克服了鎂合金在耐腐蝕性和高溫穩定性方面的傳統挑戰,使其能夠應用於關鍵動力傳動系統和外部零件。例如,2024年5月,上汽集團成功實現鎂合金電驅動系統外殼的量產,獲得業界高度讚譽。這證明了這些尖端材料的商業性可行性,並推動了貿易活動的持續成長。因此,光是2024年11月,中國鎂錠出口量就達到了22,647噸。
由於主要生產區域嚴重依賴少數地區,該市場受到嚴重限制,導致全球供應鏈出現重大脆弱性。這種集中化使國際製造商面臨巨大的採購風險,局部地區的突發事件,例如監管變化或能源短缺,都可能迅速演變為全球供應危機。因此,下游產業,尤其是汽車和航太產業,往往不願意擴大鎂合金的使用量,因為它們無法獲得長期生產計畫所需的穩定且有保障的價格結構。這種地域集中進一步加劇了價格波動,因為市場穩定依賴特定地區的持續運營,而不是多元化的全球網路。預計到2024年,光是榆林地區就將佔中國原生鎂總產量的約62.6%,凸顯了這種極度集中。這意味著,單一地區的環境法規或電力發行限制的實施,都可能對全球供應造成不成比例的限制,從而導致供應的不確定性。因此,鎂合金與鋁等現成替代品相比,成本競爭力較弱,阻礙了其在對成本敏感的應用領域中得到更廣泛的商業性應用。
由於大規模一體式壓鑄技術的應用,全球鎂合金錠市場正在經歷一場變革。這項製造技術的創新使得生產大型單體結構件成為可能,取代了諸如橫樑和後底盤等複雜的多部件組裝。汽車製造商正利用先進的半固體射出成型成型技術來大幅降低車輛重量和組裝成本,這促使主要合金生產商進行大規模的基礎設施升級。例如,寶武鎂業於2025年11月在其南京和重慶工廠成功運作了年產能3500噸的新型半固體鑄造生產線,以支持這些大規模一體式零件的大規模生產。同時,另一個重要趨勢是該產業正向環保、低碳的鎂製造製程轉型,使上游供應鏈與全球脫碳需求保持一致。製造商正迅速從高能耗的傳統生產方式轉向現代化、垂直整合的生產設施,以降低監管風險並確保出口可行性。政府針對低效率產能的措施加速了這項轉變。這種向環保合規生產的整合有效穩定了市場動態,並降低了傳統分散式供應鏈所帶來的波動性。例如,隨著產業向這些受監管的永續營運模式轉型,中國的「防止國內競爭」措施幫助穩定了2025年8月的月出口量,使其達到38,600噸。
The Global Magnesium Alloy Ingot Market is projected to grow from USD 2216.02 Million in 2025 to USD 2887.49 Million by 2031, exhibiting a compound annual growth rate (CAGR) of 4.51%. These solid metal castings, primarily magnesium alloyed with elements such as aluminum, zinc, and manganese to enhance mechanical properties, are crucially demanded by the automotive and aerospace sectors. The imperative for weight reduction in these industries, aimed at improving fuel efficiency and extending electric vehicle range, underpins this demand. In 2024, China's primary magnesium production reached 1,025,800 tonnes, marking a 24% increase from the previous year, which highlights the significant manufacturing capacity supporting downstream industries. Despite this growth, the market faces considerable challenges, particularly regarding supply chain concentration and associated price volatility. The heavy reliance on limited geographic regions for primary production creates vulnerabilities to geopolitical shifts and regulatory changes, potentially disrupting stable procurement for international manufacturers. Furthermore, rising energy costs and stringent environmental compliance standards in major producing nations threaten to inflate production expenses, which could hinder the broader adoption of these alloys in cost-sensitive commercial applications.

Market Driver
A primary catalyst for the magnesium alloy ingot sector is the rapid expansion of the Electric Vehicle (EV) market, necessitating range optimization. As automakers electrify their fleets, the substantial weight of battery packs requires significant mass reduction in structural components to maximize driving range and performance. Magnesium alloys, offering the best strength-to-weight ratio among structural metals, are increasingly utilized for critical EV components such as battery enclosures, motor housings, and cross-car beams, directly fueling the consumption of raw magnesium ingots. This trend is underscored by a 24.78% year-on-year surge in China's magnesium ingot exports, reaching 242,200 tonnes from January to November 2024, as global automotive OEMs actively secure supplies for lightweighting initiatives. Simultaneously, advancements in alloy technology are enhancing corrosion resistance and castability, thereby expanding the material's application scope. Innovations in semi-solid injection molding and the development of new alloy grades have successfully addressed historical limitations concerning corrosion and high-temperature stability, enabling magnesium's use in critical powertrain and exterior applications. For instance, in May 2024, SAIC Motor received industry recognition for mass-producing the first magnesium alloy cases for electric drive systems, validating the commercial viability of these advanced materials and supporting sustained trade activity, with China's magnesium ingot exports reaching 22,647 metric tonnes in November 2024 alone.
Market Challenge
The market is significantly constrained by a heavy reliance on a limited number of geographic regions for primary production, which creates acute vulnerabilities within the global supply chain. This concentration exposes international manufacturers to severe procurement risks, where localized disruptions-such as regulatory shifts or energy shortages-can swiftly escalate into global availability crises. Consequently, downstream industries, particularly in automotive and aerospace manufacturing, are often hesitant to expand their utilization of magnesium alloys due due to the inability to secure the stable, guaranteed pricing structures essential for long-term production planning. This geographic centralization further amplifies price volatility, as the market's stability hinges on the operational continuity of specific localities rather than a diversified global network. In 2024, the Yulin region alone accounted for approximately 62.6% of China's total primary magnesium output, illustrating extreme localization. This means that environmental compliance enforcement or power rationing in just one area can disproportionately restrict global supply, leading to unpredictability that erodes the cost-competitiveness of magnesium alloys against more readily available alternatives like aluminum, thereby hindering their broader commercial adoption in cost-sensitive applications.
Market Trends
The Global Magnesium Alloy Ingot Market is undergoing transformation through the adoption of large-scale integrated die-casting, often termed Gigacasting. This manufacturing innovation enables the production of massive, single-piece structural components that replace complex multi-part assemblies, such as cross-car beams and rear underbodies. Automotive OEMs are leveraging advanced semi-solid injection molding to achieve significant reductions in vehicle weight and assembly costs, driving substantial infrastructure upgrades among leading alloy producers. For example, in November 2025, Baowu Magnesium Industry successfully commissioned new semi-solid casting production lines with capacities reaching 3,500 tonnes at its Nanjing and Chongqing facilities specifically to support the mass production of these large-scale integrated components. Simultaneously, a significant trend is the industry's shift towards green and low-carbon magnesium production processes, aligning the upstream supply chain with global decarbonization mandates. Manufacturers are rapidly transitioning from energy-intensive legacy methods to modernized, vertically integrated facilities to mitigate regulatory risks and ensure export viability, a movement accelerated by government initiatives targeting inefficient capacity. This consolidation towards environmentally compliant production effectively stabilizes market dynamics and reduces the volatility associated with older, fragmented supply bases; for instance, China's "anti-internal competition" policy contributed to a stabilized monthly export volume of 38,600 tonnes in August 2025 as the sector shifted towards these regulated, sustainable operational models.
