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
Alumina ceramic material has high hardness and wear resistance,
strong corrosion resistance, high temperature resistance, corrosion
resistance and biological inertia.
So it can be used as cellphone back plate.
the properties of alumina ceramics:
|Properties||Unit||99% alumina||95% alumina|
|HV Hardness HV||MPa||1650||1400|
|Fracture Toughness||MPa *m 1/2||4.2||3.9|

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
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.
