Customized Ruby Bearing Parts With Through-Hole
Introduction
Sapphire, which is derived from the Latin Spphins, which means blue; it belongs to the corundum group of minerals in the trigonal crystal system. In the gem world, all colors of gem-grade corundum other than rubies are called sapphires.
The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.
Basic characteristics
Sapphire precision parts are generally used in the wear-resistant and high-temperature parts of instruments, meters, and equipment.
Sapphire has a hardness of 9 on the Mohs level, second only to diamond, and has good wear resistance. At the same time, it has excellent chemical stability and can resist almost any acid and alkali corrosion. In addition, the maximum temperature of sapphire reaches 2060℃. It is precisely because of the above advantages of sapphire that sapphire is used in instrumentation equipment, which can significantly increase the service life and withstand various harsh environments.
The precision parts made of sapphire include: water meter and electric meter bearing, chemical pump through valve body, textile machine stopper, etc.
Sapphire precision parts often have complex shape requirements and precise sealing requirements.
We can customize various shapes according to customers' drawings.
We also have precision, grinding, polishing and testing equipment to ensure that each product meets the demanding requirements of customers.
