<div class="htmlview paragraph">The range of properties of compacted graphite cast irons lie generally intermediate between those of flake graphite and nodular graphite cast irons and makes them attractive for a number of applications. These properties arise from the unique compacted graphite structure. The alternative ways of producing compacted graphite cast irons are reviewed, and the potential for widening the range of properties through structure control is discussed of particular importance for commercial exploitation is quality control of the production process and of the material structure and properties, and the paper contains information on these topics.</div>
