NM, UNITED STATES, February 19, 2025 /EINPresswire / -- The global compacted graphite iron (CGI) market has been gaining significant traction in recent years, driven by its unique properties and increasing demand across various industries. Compacted graphite iron, also known as vermicular graphite iron, is a type of cast iron that offers a balance of mechanical and thermal properties, making it an ideal material for a wide range of applications. With its superior strength, thermal conductivity, and durability, CGI has become a preferred choice in industries such as automotive, aerospace, construction, and heavy machinery. This article explores the current state of the compacted graphite iron market , key growth drivers, emerging trends, and future prospects.

Market Size and Growth Projections

The Compacted Graphite Iron Market was valued at approximately USD 10.17 billion in 2024 and is projected to expand from USD 10.78 billion in 2025 to USD 18.08 billion by 2034, reflecting a compound annual growth rate (CAGR) of 5.92% over the forecast period (2025–2034).

What is Compacted Graphite Iron?

Compacted graphite iron is a cast iron material that features a unique graphite morphology, which lies between that of flake graphite iron (FGI) and spheroidal graphite iron (SGI). The graphite in CGI appears as interconnected, worm-like structures, providing a combination of strength, stiffness, and thermal conductivity. This unique structure allows CGI to outperform traditional cast iron materials in terms of fatigue resistance, wear resistance, and vibration damping. As a result, CGI is increasingly being used in applications that require high performance under demanding conditions.
