Sapphire glass is different from ordinary glass mainly in terms of abrasion resistance and scope of application. The specific differences are:
1. The wear resistance is different. Sapphire glass, tungsten-titanium alloy and high-tech ceramics are all wear-resistant materials and are not easy to wear，
sapphire watch case; while ordinary glass has poor wear resistance and is easy to wear.
2. Different manufacturing materials. Ordinary glass is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added; while sapphire glass is It is made of alumina, and a small amount of titanium and iron.
3. Different uses. Ordinary glass is often used in places where wear resistance is not high, such as daily decoration; while sapphire glass is used in places that require high wear resistance, such as watches and mobile phone screens.
