Don't forget the protection of the lens | Samsung Galaxy Z Flip4 9H hardness 9H hardnesst Nano Technology NanoTechnology Scratch protection Fadefingerprints Fadefingerprints unobstructedlighting Impact-absorbing About The Lens Circle incorporates Corning glass and aerospace aluminum alloys into the lens film. Corning Glass is an aluminosilicate glass. With high durability and scratch resistance, it can withstand strong squeezing and repeated touch. With the protection of aviation aluminum alloy three-dimensional ring, Mohs hardness 9H, hard and no damage protection. What is High Alumina glass? Ultra-high pressure glass is made of aluminosilicate glass with a purity of 99.5%. The ultra-high pressure glass produced has the characteristics of high-pressure resistance and high-temperature resistance. It belongs to the alkali-free aluminosilicate glass series. Good air permeability, which is conducive to human eye observation, high softening point temperature of the glass, suitable for high and low temperature working occasions, and can be tempered and heat-treated like ordinary glass to increase the pressure resistance of the outer surface of the glass.
