Heat resistant alumina ceramic part Al2O3 ceramic component
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. Alumina ceramic is a kind of widely used ceramic. 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.
