99.99% Al2O3 Pure Sapphire Crystal Watch Case , Mens Watch Sapphire Glass Back Cover

 Sapphire Watch Case Watch glasses Back Cover

Description

Synthetic sapphire is transparent single crystal 99.99% pure Al2O3 that exhibits a unique combination of physical, chemical, electrical and optical properties: high thermal conductivity, high strength and scratch resistance, hardness (9 on the Mohs scale), transparent in wide range of wavelength, chemical inertness.

High crystal perfection, low reactivity, and appropriate unit cell size make sapphire an excellent substrate in the semiconductor industry for blue light-emitting diodes (LED).

Many manufacturers use sapphire to make watch cover and watch cases for luxory watches like Rolex. Sapphire watch cover and watch cases can also be understood as sapphire case. This synthetic sapphire makes it into case series, which has distinct characteristics and many advantages. It has high hardness, which can rival iron, copper and other tough substances, second only to diamond, It can resist the extrusion of foreign objects and prevent crushing, so as to damage the internal structural parts and cause unnecessary losses; Secondly, it has strong corrosion resistance and compression resistance, or more functions, such as waterproof and shockproof. It is because sapphire finished products have these various characteristics, which makes it one of the essential components of watch case or mobile phone window. Since it is sapphire case series, let's take a look at sapphire, Sapphire has been heard of in life, large and small. It is both naturally formed and artificially synthesized. Whether it is natural or artificially made, it has strong hardness characteristics, and its main component is aluminum oxide. What we call sapphire is blue, while the watch cover and watch cases are transparent. Why? This is because it is a transparent and colorless sapphire formed by firing pure alumina at high temperature. The high strength, high hardness and scratch resistance of this sapphire have been improved. Therefore, it is one of the indispensable components of sapphire watch mirror series. Because the cost of processing this kind of watch mirror will be higher, under high temperature firing, The consumption of ingredients and materials is very serious, so the watch composed of sapphire mirror we buy in life will be relatively expensive. The composition is the preferred material for high-end watch mirror.
