Product Description
Heat exchange alumina thermocouple ceramic insulation tube
Alumina Ceramic
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.
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.
