Electric Insulation Wear Resistant Customized Size Alumina Ceramic Block
Alumina ceramic material has high hardness and wear resistance, strong corrosion resistance, high temperature resistance, corrosion resistance and biological inertia,
so it is widely used in many fields.
This plate is made of 99.5% alumina ceramic.Because of the high hardness and brittleness,we usually take laser processing as the main method to processing the
super samll and deep hole and grooves.the smallest machining diameter is 0.05mm,
and the depth can achieve 12mm with good hole roundness and precision fine surface.
