Super Hardness Good Impact Resistance 99% Alumina Cell Phone Back Plate

Product Specification

Super Hardness Good Impact Resistance 99% Alumina Cell Phone Back Plate Customized Shape

Alumina ceramic is a precision ceramic material with good wear-resistant , and is widely used in all walks of life.The main molding methods of alumina ceramic products are dry pressing, grouting, extrusion, cold isostatic pressing, injection and tape casting. Different shapes, sizes, complex shapes and precision products need different forming methods.e alumina ceramic products sintered at high temperature can only be processed with diamond grinding technology.

99% alumina ceramic has the following performance advantages: hardness is close to sapphire, scratch resistance, delicate touch and surface gloss,its weight is 50% as stainless steel material, more scratch resistance and more anti sensitive.

The dielectric constant is 3 times as the sapphire, signal is more sensitive, especially suitable for fingerprint identification cover (compared to the 0.3mm iPhone Touch ID sapphire cover, with the same thickness, a higher degree of recognition; or equivalent recognition can be Kehou thin, thick when strength, anti fall will significantly improve).

The total cost is only 1/4 of sapphire. Also can be used to realize a mobile phone wireless charging conditions, due to the realization of wireless charging must one cannot use conductive material, that can not use metal material, and 99 alumina ceramics at room temperature is not conductive, is the ideal material.
