Composite Metal Foam (CMF) Market size was valued at USD 366 million in 2024. The market is projected to grow from USD 385 million in 2025 to USD 532 million by 2031, exhibiting a CAGR of 5.6% during the forecast period.
Composite Metal Foam (CMF) is an advanced cellular material consisting of hollow metallic spheres – typically made of carbon steel, stainless steel, or titanium – embedded in a metallic matrix composed of steel, aluminum, or other alloys. The “steel-steel” variant indicates both spheres and matrix are steel-based. These materials offer exceptional properties including high strength-to-weight ratio, energy absorption, thermal insulation, and radiation shielding.
The market growth is driven by increasing demand across aerospace, automotive, and defense sectors where lightweight yet durable materials are critical. While North America currently leads in adoption, Asia-Pacific is emerging as a high-growth region due to rapid industrialization. Key manufacturers like ERG Aerospace and Cymat Technologies are expanding production capacities to meet rising demand, particularly for nickel and aluminum-based foams which dominate current applications.
