Product Description
Silkprinting Round Domed Sapphire Crystal Wristwatch parts Watch Glass
Why Choose sapphire crystal?
Sapphire optical material has excellent thermal conductivity at low temperatures allowing single crystal Sapphire to be used in many diverse fields requiring thermal conductivity and heat radiation.
Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method.
Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond.
It can operate up to 2030C.
