From Graphite to Innovation — The Role of Polycrystalline Graphite Foils

Polycrystalline Graphite Foils (PCG’s) are among the most versatile and innovative materials in today’s high-energy research environments. These foils combine flexibility, electrical conductivity, and exceptional thermal stability — a combination that makes them indispensable for target fabrication and ion beam applications.

At ACF Metals, our PCG foils are manufactured using controlled thermal and mechanical processes that produce uniform grain structure and consistent thickness across every sheet. This ensures predictable performance and minimal variation between production batches — a critical factor for repeatable experiments and analytical reliability.

One of the key advantages of ACF’s PCG foils is their ability to maintain mechanical strength and dimensional accuracy even under elevated temperatures and heavy particle flux. Whether used in target assemblies or as backing materials for thin films, these foils resist warping, tearing, and contamination — ensuring a longer service life.

The flexibility of PCG materials allows for customized fabrication, making them suitable for specialized setups in nuclear, accelerator, and materials research laboratories. By continually refining our production techniques, ACF Metals provides researchers with graphite foils that embody both innovation and precision, supporting the growing demands of modern science.
