Product Details
95 porcelain high temperature resistant insulating ceramic positioning pin
Product Overview
Alumina has a high hardness and density, with an Inch hardness of 9, which is slightly lower than diamond. The bulk density is generally greater than 3.5 g/cm³, and some can reach 4.0g/cm³. Alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to different Al2O3 content. Among them, 99 alumina ceramic materials are used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings and ceramic seals. Parts, etc.; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts.
Widely used in coal-fired power plants, iron and steel, smelting, machinery, coal, mining, chemical, cement, port and terminal enterprises, coal transportation, conveying system, powder milling system, ash discharge, dust removal system and other large wear and tear mechanical equipment , Can provide different types of products according to different needs
