Single Crystal Sapphire (Al2O3) – Custom Machined Parts
Single crystal sapphire has a unique combination of excellent mechanical, thermal, chemical and optical properties. It retains its high strength at high temperatures. It is also chemically inert to common acids and alkali even at elevated temperatures. Combined with its wide transmission range from ultraviolet to infrared, it is the ideal material for optical components used in hostile environments.
Second only to diamond in hardness, sapphire is extremely durable and scratch & wear resistant. It is often used in making parts and components for hard wearing applications requiring high level of scratch resistance.
