MARKET INSIGHTS

Global malleable iron foundries market size was valued at USD 22.5 billion in 2025. The market is projected to grow from USD 23.1 billion in 2026 to USD 29.8 billion by 2034, exhibiting a CAGR of 2.6% during the forecast period.

Malleable iron is a specific form of cast iron that has undergone a controlled heat treatment process to enhance its physical properties, offering superior ductility compared to standard grey iron. It serves as a critical material for producing pipe fittings, flanges, and small industrial components that must withstand mechanical stress and varying temperatures.

The market growth is primarily fueled by the continuous demand from the automotive and construction industries for cost‑effective and durable materials. Furthermore, the ongoing revitalization of global infrastructure projects and the adoption of malleable iron in complex hydraulic systems are expected to drive steady demand for foundry services over the coming years.
