Cte Of Alumina Ceramic

This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance.
Cte of alumina ceramic. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications. Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature.
Maximum use temperature c. The following values are given for a temperature around 20 c. Coefficient of thermal expansion. Learn about product material coefficient of thermal expansion.
