C795 C799 Alumina Thermocouple Protection Sheath

Product detail

Alumina ceramic (also called al2o3 or aluminum oxide ceramic) is widely applied in high temperature fields because of their good resistance to high temperature, it can withstand high temperature up to 1800℃, in addtion to its stable chemical properties, high mechanical strength and electrical insulation, Ceramic tubes made of alumina are commonly utilized in high-temperature furnaces, thermocouples' closed-end or multi-hole insulating rods, and corona electrode's square ceramic tubes. Mascera employs extrusion molding technology to manufacture ceramic tubes of up to 2000mm in length, and we also provide custom sizing options. Please get in touch with us for any specific requirements.
