The alumina ceramics produced by our company are made of alumina (AL2O3) as the main material. High mechanical strength, high insulation strength, the same hardness as corundum, wear resistance is comparable to super hard alloy. It can be used for bio-ceramics, electronic devices such as high-voltage switch shell insulation materials, mechanical parts such as sealing ring valve parts, wear-resistant materials such as wear-resistant ceramic balls and rods, high-temperature devices such as high-temperature liquid delivery pipes and so on. Ultrasound is required for washing. Superior performance, more and more widely used to meet the needs of daily use and special performance. Widely used in lighting appliances, electric appliances, petrochemicals, machinery, textiles, automobiles and other industries, the specifications can be customized according to customer needs.
