Sapphire Rod

Sapphire Rod Description

Sapphire Rod is produced as a uniform single-crystal cylinder with excellent hardness, optical stability, and resistance to chemical corrosion. Its consistent structure makes it suitable for slicing, polishing, and machining into precision parts such as optical substrates, mechanical components, and electronic devices. With customizable crystal orientations and a wide range of size options, it supports applications requiring strong durability and high thermal tolerance.
