Laser cutting 95% alumina ceramic plate wear resistant alumina ceramic substrate
Alumina ceramic is a kind of material based on alumina (Al2O3),
which is used in thick film integrated circuit. Alumina ceramics
have good conductivity, mechanical strength and high temperature
resistance. It needs to be noted that ultrasonic cleaning is
needed.Because of its superior performance, it has been widely used
in modern society, meeting the needs of daily use and special
performance
Features & Advantages
1. High hardness.
2. High heat resistance: alumina ceramic has excellentthermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
3. Good wear resistance: alumina ceramic is the material of choice
for alumina wear parts.
4. High electrical resistivity: alumina is an electrically
insulating material.
5. High corrosion resistance: it is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
