More info

Sapphire Rod is produced as a high-purity single-crystal cylinder, typically grown along the A-axis and machined to expose the C-plane (0001), which is widely used in LED and optical applications. These rods offer stable structure, consistent geometry, and strong mechanical properties suitable for slicing, polishing, and secondary fabrication. Diameters from 2 inches to 8 inches are available, along with custom orientations and dimensions to meet specific technical requirements. Heeger Materials provides high-quality Sapphire Rods for advanced optical and electronic processing.
