汽車曲軸市場概況
2024 年全球汽車曲軸市場規模估計為 49.811 億美元,預計到 2033 年將達到 72.794 億美元,2025 年至 2033 年的複合年成長率為 4.5%。隨著新興市場內燃機 (ICE) 汽車和商用車產量不斷增加、對輕質高強度曲軸材料的需求不斷成長,以及精密鍛造和數控加工等先進製造技術的融合,汽車曲軸市場發展勢頭強勁。
隨著原始設備製造商 (OEM) 專注於提高引擎效率、耐用性和性能,曲軸正被重新設計,以追求更嚴格的公差和更優異的冶金性能。此外,高性能合金和表面處理的採用也有助於製造商滿足不斷變化的法規和性能基準。人們對坯料曲軸的興趣日益濃厚,尤其是在高性能電動車和原型電動車領域,其卓越的疲勞強度和可自訂性帶來了巨大的機會。然而,在不同的載荷和材料條件下保持尺寸精度和抗疲勞性是一項工程挑戰。
新興市場內燃機車 (ICE) 和商用車產量的不斷成長,推動了汽車曲軸的需求。中國、日本和印度等國的汽車製造業正經歷強勁成長,這得益於強勁的國內需求和不斷成長的出口。根據印度品牌資產基金會的數據,到 2023 年,印度的汽車年產量將達到 2,590 萬輛,其中二輪車和乘用車將佔主要佔有率。預計 2025 年(4 月至 9 月)的汽車產量將超過 1,560 萬輛,這反映了汽車產業的韌性。內燃機汽車和商用車產量的持續成長,正在推動對曲軸零件的需求。
如今,製造商越來越注重提高燃油經濟性、減少排放氣體和提升引擎性能。使用鍛造鋼、鋼坯和鋁合金等先進材料可以顯著減輕重量,同時保持強度和耐用性,以承受引擎的高負荷。輕量化曲軸在高性能汽車、混合模式以及燃油經濟性和運行效率至關重要的商業應用中尤其重要。例如,高性能跑車和豪華車通常採用鋼坯曲軸來最佳化功率重量比。
精密鍛造提高了曲軸的機械性能,確保了現代引擎在高應力下運作所必需的抗疲勞性和結構完整性。數控加工可實現更嚴格的公差和更複雜的幾何形狀,從而生產出符合嚴格原始設備製造商 (OEM) 規格的曲軸。這項技術轉變支持縮短生產週期、提高成本效益,並支援各種車型的客製化生產。例如,高性能轎車和輕型商用車製造商擴大採用精密鍛造曲軸來滿足耐用性和輕量化要求,這使得這些技術在推動市場擴張方面日益重要。
坯料曲軸由高強度鋼實心塊加工而成,在極端條件下具有卓越的耐用性、精度和性能,是高馬力應用和賽車運動的理想選擇。此外,隨著汽車製造商和電動車新興企業開發高性能電動動力傳動系統,坯料曲軸正被考慮用於混合動力汽車和增程器汽車應用,因為這些應用對強度、輕量化和可靠性至關重要。這一趨勢為專業曲軸製造商開闢了新的途徑,他們瞄準的是賽車、豪華跑車以及追求更高動力和效率的下一代電動和混合動力汽車等利基市場。
曲軸主要採用合金鋼製造,由於全球大宗商品市場的波動,合金鋼價格持續不穩定。例如,預計全球平均鋼材價格將從2020年的每噸約500美元上漲至2024年的750-800美元以上,將顯著影響製造成本。此外,鍛造製程需要大量的能源投入,尤其是在精密鍛造和熱處理階段,這進一步增加了營運成本。這些成本壓力對中小型製造商來說尤其具有挑戰性,限制了它們在全球市場上的競爭和擴張能力。
Automotive Crankshaft Market Summary
The global automotive crankshaft market size was estimated at USD 4981.1 million in 2024, and is projected to reach USD 7279.4 million by 2033, growing at a CAGR of 4.5% from 2025 to 2033. The automotive crankshaft market is gaining momentum, driven by increasing production of internal combustion engine (ICE) and commercial vehicles in emerging markets, rising demand for lightweight yet high-strength crankshaft materials, and the integration of advanced manufacturing technologies such as precision forging and CNC machining.
As OEMs focus on improving engine efficiency, durability, and performance, crankshafts are being redesigned with tighter tolerances and enhanced metallurgical properties. Additionally, the adoption of high-performance alloys and surface treatments is helping manufacturers meet evolving regulatory and performance benchmarks. The growing interest in billet crankshafts, particularly for high-performance and prototype electric vehicles, presents a significant opportunity due to their superior fatigue strength and customizability. However, maintaining dimensional accuracy and fatigue resistance across varying loads and materials continues to pose an engineering challenge.
The increasing production of internal combustion engines (ICE) and commercial vehicles in emerging markets is significantly driving the demand for automotive crankshafts. Countries including China, Japan, and India are witnessing robust growth in vehicle manufacturing, supported by strong domestic demand and rising export activities. According to the India Brand Equity Foundation, India's annual automobile production in 2023 reached 25.9 million units, with two-wheelers and passenger cars accounting for the majority share. In 2025 (April-September), total vehicle production surpassed 15.6 million units, reflecting the resilience of the automotive sector. This sustained growth in ICE and commercial vehicle output is boosting the need for crankshaft components, as manufacturers scale up to meet both local and global market requirements.
Today, manufacturers are increasingly focusing on improving fuel efficiency, reducing emissions, and enhancing engine performance. The use of advanced materials such as forged steel, billet steel, and aluminum alloys enables significant weight reduction while maintaining the required strength and durability to withstand high engine loads. Lightweight crankshafts are particularly valuable in performance vehicles, hybrid models, and commercial applications where fuel economy and operational efficiency are critical. For instance, high-performance sports cars and premium vehicles often employ billet steel crankshafts to optimize power-to-weight ratios.
Precision forging enhances the mechanical properties of crankshafts, ensuring greater fatigue resistance and structural integrity, which are essential for modern engines operating under high stress. CNC machining allows for tighter tolerances and complex geometries, resulting in crankshafts that meet stringent OEM specifications. This technological shift supports faster production cycles, cost-efficiency, and customization for diverse vehicle types. For example, high-performance and commercial vehicle manufacturers increasingly adopt precision-forged crankshafts to meet durability and light-weighting requirements, reinforcing the relevance of these technologies in driving market expansion.
Billet crankshafts, machined from a solid piece of high-strength steel, offer superior durability, precision, and performance under extreme conditions, making them ideal for high-horsepower applications and motorsports. Additionally, as automakers and EV start-ups increasingly develop high-performance electric powertrains, billet crankshafts are being explored for hybrid and range-extender applications where strength, weight reduction, and reliability are critical. This trend is opening up new avenues for specialized crankshaft manufacturers targeting niche markets such as racing, luxury sports cars, and next-generation electric or hybrid vehicles seeking enhanced power delivery and efficiency.
Crankshafts are predominantly manufactured using steel alloys, the prices of which have remained volatile due to fluctuations in global commodity markets. For instance, the average global price of steel rose from approximately USD 500 per metric ton in 2020 to over USD 750-800 per metric ton in 2024, significantly impacting manufacturing costs. Additionally, forging processes require substantial energy inputs, particularly in precision forging and heat treatment stages, further adding to operational expenses. These cost pressures are especially challenging for small and mid-sized manufacturers, limiting their competitiveness and scalability in global markets.
