Rods out of Sapphire are widely used in medical devices, accurate machine and inspection instruments, due to its exceptional properties of high hardness, high strength, scratch resistance, high temperature resistance, purity, chemical durability and superior radiation stability. Sapphire rod is perfect material for high temperature application with no change to its shape and dimension because of its extreme High Softening Point over 2000�°C. Sapphire rod is chemically inert and resistant to attack from most processing environments, such as Acid and Alkalis at temperatures up to ~1,000 C. Sapphire rod is bio-inert. It is the ideal material for bio-engineering, dental and medical bone implants.
