Audited Supplier Porcelain ceramic tubes are generally used as a standard protective component, so we have a wide range of stock available at our factory to meet our customers' urgent shipment needs. Alumina has a wide range of applications, and its purity is selected based on the application environment. If the customer needs other purities, our factory can also prepare them.
75% alumina ceramic means that the content of Al2O3 in the material is about 75%. 75% alumina has good electrical insulation properties, high heat resistance and chemical corrosion resistance, and can maintain its stable insulation property even in high temperatures and harsh environments.
Main Characteristics of 75% Alumina Ceramic Tubes
1. Outstanding wear resistance, over 276 times in comparison with stainless steel.
2. Great mechanical properties, with diamond-like hardness and dense body.
3. Exceptional corrosion resistance, can withstand various strong acid and alkali like HCL and H2SO4.
4. Extraordinary electrical insulation, suitable for high voltage and high-current applications.
