The Types segment classifies amorphous metal ribbons by alloy composition, thickness, and surface treatment, each influencing cost structure and adoption rate. Fe‑based alloys, comprising roughly 45 % of production, are favored for large‑scale transformer cores due to their balance of magnetic performance and material cost. Co‑based ribbons, about 30 % of output, deliver superior high‑frequency characteristics, making them essential for aerospace‑grade sensors and high‑speed actuators. Ni‑based variants, representing 15 %, are niche but critical in medical imaging where corrosion resistance and biocompatibility are paramount. Thickness categories—thin (≤10 µm) and thick (>10 µm)—split the market 55 % to 45 %, with thin ribbons enabling higher frequency operation and thick ribbons offering mechanical robustness for power applications. Surface finishes, coated versus uncoated, further differentiate value, where coated products (≈40 %) command premium pricing for enhanced durability in harsh environments. This market taxonomy of Types illustrates how material attributes allocate revenue across the Amorphous Metal Ribbons segmentation.
