99% alumina isolator ceramic coil yarn seal ring
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Because of its high temperature resistance, corrosion resistance, high strength and other properties, it is used as a steel sliding nozzle to smelt rare metals, special alloys, Ceramic Disc high-purity metals, glass-drawn wires and vessels; various high-temperature furnaces, such as refractory materials, ceramics , lining of iron-making blast furnace (wall and tube); physicochemical vessels, spark plugs, heat-resistant anti-oxidation coating. Low-silicon sintered corundum bricks with Ceramic Disc SiO2 less than 0.5% are special furnace linings for carbon black, boron chemical, fertilizer, ammonia synthesis reactor and gasification furnace. Due to its high hardness, good wear resistance and high strength, it is used in Ceramic Disc various chemical Ceramic Disc reactors for various reaction vessels and pipes, chemical pump parts; as mechanical parts, various molds, such as wire drawing die, pencil core Mold nozzles, etc.; for tools, abrasives, bulletproof materials, human joints, seal rings, etc.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
