Well-Grinded Smooth Surface 99% Alumina Insulating Ceramic Rod
Alumina rod is made of aluminum oxide (Al2O3) ceramic – a fine ceramic material that is widely used in various industries. Aluminum oxide rod has superb performance in electrical insulation, high chemical resistance, and low thermal expansion.According to actual application and customer's requirement, the purities vary from 95%-99.7% and the forming methods will be different. The forming methods applied in our plant include dry pressing, isostatic pressing, injection moulding, extrusion moulding. With experienced engineers and talented workers, we are confident to offer high quality, high precision, complex components for customers worldwide.
Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
