The 400 MPa segment dominated the compacted graphite iron market with a 34.6% share in 2024. This grade is widely used in automotive engine blocks, cylinder heads, and heavy machinery components due to its balance of tensile strength, thermal conductivity, and machinability. Its durability supports high-performance engines under extreme temperatures and pressure. The rising demand for lightweight yet strong materials in vehicle manufacturing continues to drive the use of 400 MPa CGI. Growing production of commercial vehicles further strengthens the segment’s leadership in global applications.
For instance, SinterCast reports CGI delivers at least 75% higher tensile strength and 45% higher stiffness than gray iron, supporting ~400 MPa class engine blocks in series production.
By Product
The nodules segment held the largest share of 59.2% in 2024. Its dominance is driven by the superior strength and elasticity that nodular structures provide, enhancing performance under cyclic stress and vibration. Nodular CGI products are preferred in diesel and gasoline engine parts due to better fatigue resistance compared to spheroid forms. Increasing engine downsizing trends and the shift toward higher power densities in automotive design are fueling demand for nodular CGI. This structure also offers improved casting properties, enabling cost-efficient production for mass manufacturing.
For instance, Impro Precision produces CGI sand-cast components weighing 40–300 kg and consistently achieves over 90% vermicular graphite, matching nodular performance needs.
By Application
The automotive segment led the compacted graphite iron market with a 67.8% share in 2024. CGI’s high stiffness, thermal fatigue resistance, and reduced weight make it ideal for engine blocks, exhaust manifolds, and brake components. The material enables improved fuel efficiency and lower CO₂ emissions, aligning with stringent emission norms in Europe and North America. Rapid electrification and hybrid vehicle manufacturing are further promoting CGI adoption in motor housings and structural parts. Expanding production by global OEMs across China and Germany continues to reinforce automotive sector dominance.
Key Growth Drivers
Rising Adoption in Automotive Engine Manufacturing
The growing use of compacted graphite iron in engine blocks and cylinder heads is a major driver of market growth. Automakers favor CGI for its high strength, thermal resistance, and lightweight properties, improving fuel efficiency and engine durability. Its compatibility with both diesel and gasoline engines supports its integration in hybrid and internal combustion vehicles. Increasing demand for efficient, low-emission engines is further accelerating its adoption across the automotive sector.
For instance, Ford’s 6.7 L PowerStroke diesel with a CGI block reached 400 hp and 1,085 Nm after a software update, underscoring durability for higher outputs.
Expanding Use in Power Generation Equipment
The power generation industry is increasingly utilizing compacted graphite iron for turbine housings, engine components, and heat exchangers. Its ability to handle high pressure and temperature while maintaining structural integrity enhances operational reliability. As global power demand rises, especially in developing economies, the use of CGI components is expanding in both conventional and renewable power plants. This material’s long service life and low maintenance needs strengthen its role in energy infrastructure.
For instance, Rolls-Royce Power Systems cast CGI engine frames weighing 9–17 tons, demonstrating thermal-fatigue resistance for heavy-duty power units.
Growth in Heavy Machinery and Construction Equipment
Heavy-duty machinery and construction equipment manufacturers are adopting CGI for components that require enhanced fatigue strength and vibration resistance. Its performance in load-bearing applications such as engine blocks, crankcases, and structural supports ensures longer lifespan and reduced downtime. The ongoing expansion of infrastructure projects and industrialization in Asia-Pacific further drives demand. CGI’s superior mechanical characteristics compared to gray iron make it a preferred choice for high-stress applications in construction machinery.
Key Trends & Opportunities
Shift Toward Lightweight and Sustainable Materials
The global focus on sustainability and fuel efficiency is encouraging manufacturers to use CGI as a substitute for heavier metals. Its lighter weight without compromising strength supports carbon reduction initiatives in transportation and industrial sectors. The combination of recyclability and reduced energy consumption in production enhances its environmental appeal. These factors position CGI as a vital material for future green manufacturing trends across industries.
For instance, Audi’s CGI diesel blocks achieved about a 10% weight reduction versus conventional cast iron while maintaining strength for efficiency gains.
Integration of Advanced Casting Technologies
The adoption of advanced casting and metallurgical control technologies is improving the consistency and mechanical performance of CGI. Automation and real-time process monitoring are enabling higher precision in production. Manufacturers are investing in digital foundry systems and thermal management techniques to enhance yield and reduce defects. These technological advances are opening new opportunities for high-performance CGI components in automotive and industrial sectors.
For instance, Tupy has demonstrated the capability to produce Compacted Graphite Iron (CGI) engine blocks with a production cylinder-block nominal wall thickness of 3.5 mm, but has also achieved a minimum wall thickness of 2.5 mm in high-volume series production for specific gasoline V6 engines (e.g., Ford Nano V6 engine program).
Expansion in Electric Vehicle Applications
The transition toward electric vehicles presents new opportunities for CGI in motor housings, battery casings, and structural frames. Its thermal conductivity and strength make it suitable for managing heat and mechanical stress in EV systems. Automakers are exploring CGI to optimize efficiency while maintaining durability. The growing EV production in China, the U.S., and Europe is expected to expand its market scope over the coming years.
Key Challenges
High Production and Processing Costs
Producing compacted graphite iron requires precise metallurgical control and specialized equipment, leading to higher manufacturing costs. The complexity of maintaining graphite morphology adds to process expenses compared to gray iron. Smaller foundries face challenges in scaling CGI production economically. These factors limit widespread adoption, particularly in cost-sensitive industries, affecting market penetration in developing regions.
