Sapphire Plate


Sapphire is a single crystal of alumina, and has outstanding characteristics such as hardness, corrosion-resistance, and high thermal conductivity. Moreover, since it is transparent, it can be used for semiconductor wafers and sensor covers, and its demonstrated strength makes it suitable for broad uses under harsh environments, such as various laboratory visualization windows, and infrared transmission windows.
It is also widely used for watch exteriors, and has been adopted for use in exterior parts of smartphones, smart watches, and new product designs.
We respond to various requests regarding sapphire, such as size, thickness, polished finish, small-quantity prototypes, and mass production.
We also take upsizing, thinness/thickness, planarization, etc. into consideration, so please do not hesitate to ask.
