WHY ARE SAPPHIRE WINDOWS SUCH HIGH PERFORMERS?
Sapphire windows and flat stock are incredibly hard, strong and wear resistant:
A sapphire window can be exposed to extreme abradants such as sand and particulates with minimal effect on the clarity of the window. This makes sapphire windows the ideal material for a variety of applications such as: Aerospace windows, downhole and drilling vision systems, inspection windows, watch crystals and gun sights.
Sapphire windows can take pressure like no other clear material, making sapphire windows the go-to transparent material for high-pressure vessels, deep sea windows and sight glasses. Combined with the exceptional thermal and chemical performance of sapphire, a sapphire window is the ideal transparency for pressurized in-process, deep sea and equipment sensors.
Sapphire flats and wear parts are used in applications in which wear is a problem. Systems like canning machines, slide plates, V-blocks, flat bearings and pushers utilize sapphire flats and blocks to extend the lifetime of the equipment and reduce downtime.
