The alumina liner produced by King Kong New Materials Co., Ltd. is mainly made of alumina (AL2O3), which has good chemical resistance and molten metal resistance, high temperature resistance, good finish, thermal stability, and low thermal expansion coefficient. , Good thermal conductivity, high mechanical strength, high insulation strength, the same hardness as corundum, and abrasion resistance comparable to superhard alloys. It can be used in bioceramics, electronic devices such as high-voltage switch shell insulation materials, mechanical parts such as seal ring valve parts, wear-resistant materials such as wear-resistant ceramic balls and rods, high-temperature devices such as high-temperature liquid delivery pipes. Ultrasonic is required for washing. Superior performance, more and more applications, to meet the needs of daily use and special performance.
