Alumina Ceramic Plates Sheets Customized Al2O3 Alumina Ceramic Plate Sheet with High temperature resistance


Alumina ceramic plate is a ceramic material with alumina (Al2O3) as the main body, which is used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required.
Alumina ceramic plate is a kind of widely used ceramics. Because of its superior performance, it has been widely used in the field of modern industrial society and meets various needs of daily use and special properties.

Features of alumina ceramic plate:
1. High hardness
According to the Shanghai Institute of Silicate Research, Chinese Academy of Sciences, the Rockwell hardness of alumina ceramic plate is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.
2. Excellent wear resistance
The wear resistance of alumina ceramic plate is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. Under the same working conditions, the service life of the equipment can be extended by at least ten times.
3. Light weight
Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the equipment load.
4. High melting point
Alumina has a high melting point, high hardness and high mechanical strength, although the mechanical strength temperature is reduced to over 1000 °C. The thermal shock stability decreases due to the relatively large increase in the thermal expansion coefficient.
5. Insulation and acid resistance
Alumina is an electrically insulating material with high electrical resistivity. It also has good chemical stability of alumina, so it has good corrosion resistance. Alumina is insoluble in water, only slightly soluble in strong acid and alkaline aqueous solutions.
Mingrui Ceramics has more than 30,000 square meters of workshops, rich processing experience and advanced equipment. It provides alumina ceramic plates for customers, providing drilling, cutting, carving, polishing, tapping and other processing.
