Aluminum oxide is also known as: aluminum oxide(Chemical formula: Al2O3), Alumina ceramic plate is a ceramic material based on aluminum oxide (Al2O3), 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 widely used ceramic. Because of its superior performance, it has been used in modern industrial society. It is becoming more and more widely used to meet various needs of daily use and special performance.
Alumina ceramic (Al2O3) Board's features:
1. High hardness
As determined by a research institute, the Rockwell hardness of aluminum oxide ceramic plates is HRA80-90, which is second only to diamond and far exceeds the resistance of wear-resistant steel and stainless steel. Grinding performance.
2. Excellent wear resistance
According to a powder metallurgy research institute, the wear resistance of aluminum oxide ceramic plates is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
According to our customer tracking surveys over more than ten years, 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 that of steel, which can greatly reduce the load on equipment.
4. High melting point
Alumina(Al2O3)Has high melting point, high hardness and high mechanical strength, although the mechanical strength temperature is reduced to more than 1000°C. Due to the relatively large increase in thermal expansion coefficient, the thermal shock stability is reduced.
5. Insulation and acid resistance
Alumina(Al2O3)It is an electrically insulating material with high resistivity. It also has good chemical stability, so it has good corrosion resistance, is insoluble in water, and is only slightly soluble in strong acid and alkaline aqueous solutions.
